Can the steering wheel airbag be permanently removed from cover on 08 tahoe. Is it under pressure to where if I take the 4 nuts in back its gonna blow

To remove the steering wheel cover on a 2019 Hino Dyna 2.5 RON, you will need to follow these steps:

1. Locate the steering wheel cover release lever: This is typically located on the back of the steering wheel, near the bottom. It will be a small lever that you can pull down to release the cover.
2. Release the steering wheel cover: Once you have located the release lever, pull it down to release the cover. It should come off easily.
3. Remove the cover: Once the cover is released, you can remove it from the steering wheel.
4. Disconnect the airbag connector: Before you remove the steering wheel, you will need to disconnect the airbag connector. This is located at the back of the steering wheel. Disconnect it by pressing the release tab and pulling it out.
5. Remove the steering wheel: Now, you can remove the steering wheel by removing the steering wheel nut with a steering wheel puller or a steering wheel lock plate tool.
6. Reinstallation: reverse the process to reinstall the steering wheel cover.

It's important to note that these steps may not be the same for all models, so it's best to consult your owner's manual or take it to a professional mechanic for further assistance.
Also, take care when handling the airbag, disconnecting it could cause it to deploy. If you are not comfortable with the process please seek professional help.

Before you do any work turn you steering to the 'straight ahead position.
This job will depend on if yours is fitted with an airbag. The versions with NO airbag usually have a push fit centre cap you can usually 'Gently' lever out to get access to the mounting nut.
The versions WITH an airbag usually have the centre cover bolted into place.
**If yours has an airbag REMOVE the battery wire BEFORE you start to prevent the airbag going off accidentally.** The heads for these bolts are on the back of the steering wheel and often in deep holes to hide them, so you'll be working blind trying to get them out. Different companies use different styles of bolt so the heads could be a cross head screw, a hex head (Allen key?) or a torx bolt so try one of each.
Once the bolts are out, CAREFULLY lift the airbag out and CAREFULLY disconnect the wire to the airbag. This is the trigger wire which make the airbag detonate. Put it safely to one side, I usually tuck it under the vehicle for safety.
Removing the actual steering wheel is the same for both types. There is a large nut in the centre holding the steering wheel in place. This nut will be tight so you might need a helper to hold the steering wheel still while you use a socket to loosen the nut the first half turn. DO NOT take the nut all the way off, leave it on two or three turns. This stops the wheel hitting you in the face if it comes off suddenly. Rock the wheel as you pull on it. It should come free with a little bit of effort. Remove the nut all the way off. Pay attention to where the airbag wire goes as you lift the old wheel off.
Refitting is the opposite of the above method. First thread the airbag wire into place, Position the wheel so it sits straight. Then fit the nut by hand until finger tight then tighten with a socket. The nut pushes the steering wheel into place so recheck that the nut does not unscrew easily. Refit the airbag wire to the airbag, remount the airbag and reconnect the battery.

Begin by reading the precautions and method of removing the airbag in the relevant repair manual and then follow the steps for removing the steering wheel. Some steering wheels require a removal tool.

Airbags are potentially very dangerous and must be handled correctly at all times. There is a short video on YouTube adequately showing just how powerful they are.

check to see if it takes the same amount of turns to the left as it does the right. if it dose then you will need to remove the steering wheel nut under the airbag/ steering wheel cover. (disconnect the battery for 15 min before starting to remove this with airbag fitted.) if turns are not even then the steering is not set in the correct line up and needs retracking to set back up.

1
Turn on your car. Turn the steering wheel so the front tires are pointing directly forward. Turn off your car.
2

Pop the hood on your car and disconnect the black and red battery cables from the battery with pliers. By disconnecting the battery you will prevent the airbag and horn from malfunctioning or blowing.

3 Take the center cover off of your steering wheel. There should be four to six screws on the back side of the steering wheel. Unscrew these, then pry the cover off with a flathead screwdriver.

4 Remove the retaining clip on the center of your steering wheel with pliers. Place the correct size socket on the retaining nut, and loosen the nut, unscrewing it one turn.

5 Lie back in the seat and prop your knees under the bottom/sides of the steering wheel. Apply pressure on the back side of the steering wheel with your knees by pushing on your toes.

6 Place the rubber mallet over the retaining nut with your left hand. Apply pressure with your knees. With your right hand, bang on top of the rubber mallet until the steering wheel pops loose.

7

Unscrew the retaining nut completely and remove the steering wheel.

The 2007 and up Avalanche, Escalade, Trailblazer, and other GM trucks changed the design of the bottom of the steering shaft. For no discernible reason, it has a horseshoe cup at the bottom of the shaft that prevents just sliding the old sensor off and putting the new one on like in 2006 and previous models. Therefore the entire steering column has to come out of the truck which is, to say, highly annoying.
Disconnect battery and ground negative lead cable to the frame or leave disconnected for 10 minute to discharge ABS system.

Pull steering wheel ABS cover - 2 small alan wrench holes on either side of the airbag, spring-loaded, pull gently while turning the wrench.

Disconnect both airbag clips (don't lose the retaining clips!) and remove airbag.

Remove lower plastic knee trim (where your knee or shin would touch at the bottom of the kick panel).

Disconnect all steering shaft electrical connectors - there's quite a few.

Under steering column, unbolt upper driveshaft 15mm nut.

Remove 4 16mm steering wheel nuts.

Pull steering wheel out of car, lay on bench.

Remove steering wheel shaft upper protective sleeve (the part that has the horseshoe end shape that prevents the SWPS from sliding off when you're trying to remove it that serves no useful purpose except to turn a 15 minute job into an hour and a half of irritation).

Gently unclip 3 retaining clips of SWPS rear cover (4 o'clock, 7 o'clock, and 12 o'clock on the shaft), slide off, then get a screwdriver in behind the old sensor and gently move it backwards a little so you can get your fingers on it, then slide it off.

Put new sensor on exactly the way the old one was on. Note, DO NOT remove pin until this assembly is back in the car and connected to the electrical harness.

Slide SWPS cover back onto shaft but do not clip into place.

Put steering wheel back in car, connect all bolts and wire harnesses.

Remove pin.

Re-install plastic cover.

Start car, drive to dealership, hook up to Tech 2 and have them run the full SWPS re-learn procedure, which they will probably charge you an hour of labor for anyway, then take your half hour of saved labor money and go buy yourself lunch.

Alternately, save several hours of cursing, make a turkey sandwhich at home to save eating out lunch costs, and let dealer do the whole thing.

For this procedure you will need a 6mm Allen key or socket, long no. 1 phillips screwdriver, 24mm socket with extension and ratchet handle.

Park the vehicle and make sure the front wheels are straight and the steering wheel centred. Remove the negative battery terminal (make sure you have the radio code first!). Under no circumstances is the airbag to be removed with the battery still connected. Serious injury can result!!

Loosen the two 6mm Allen bolts on the back of the steering wheel and CAREFULLY remove the airbag by pulling straight out on the orange connector on the back of the airbag. Always store the airbag, when removed from the vehicle, with the side facing the driver in the UP position, preferably out of the vehicle.

Loosen and remove the 24mm nut in the centre of the steering wheel. Make note of the position of the wheel relative to the steering shaft with a marker or scribe. Do not remove the steering wheel from the shaft as yet. Next remove the two phillips screws from the recessed holes in the bottom steering column cover. Next, remove the upper steering column cover and disconnect the two wiring connectors that come from the back of the steering wheel. Carefully remove the wires from the retainers on the steering column. With those two wires disconnected, remove the steering wheel by pulling it straight off towards you. Place the steering wheel on a bench or other flat surface so the wiring and connectors are not damaged.

Installation is in the reverse order.

Read this carefully, in total, before you begin.

With car wheels aimed straight ahead, disconnect the neg. battery terminal (if you have an anti-theft radio, make sure you have the code, because you will need it.)

Wait three minutes before proceeding to allow the airbag’s backup power supply to be depleted.

Remove the access plate from the lower steering column cover and remove the short connector from the access plate (the short connector is stowed on the inside of the access plate. It is a little device that is used especially for this purpose)

Unplug the airbag module-to-cable reel connector (yellow) and plug the short connector into the airbag module side of this connection to disable the airbag.

Remove the access panels from each side of the back of the steering wheel cover, then remove both of the torx screws (you’ll need a torx screwdriver) that retain the airbag module to the steering wheel.

Pull the module off the steering wheel and CAREFULLY set it aside with the trim side facing up.

Unplug the electrical connector for the horn, and, if you have it, for the cruise control.

Remove the steering wheel retaining nut. Paint or scribe a mark indicating the relationship of the steering wheel hub to the steering shaft.

Remove the steering wheel with a steering wheel puller. DO NOT turn the steering shaft while the steering wheel is removed. If you do so, the airbag reel could be damaged.

Reinstallation is the reverse of the removal, making sure the cable reel is centered with the car wheels straight ahead (if you haven't moved the shaft, that should not be a problem), and making sure that the locating pins on the steering column engage the holes in the back of the steering wheel. Put the nut back. Torque it (36 ft. lbs). Reconnect horn and cruise control. Replace airbag, tighten torx screws. Reconnect airbag and put short connector back in access plate. Reconnect neg. battery cable.

Hope this helps you.

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury or death.
