SOURCE: Rear Axle Bearing Replacement

That absolutely sounds like an axle (wheel) bearing. Jack up that corner of the truck and grab the top and bottom of the wheel, and shake like crazy. If you have any play whatsoever, it's a sign of a bad bearing (although you could have a bad one and not have any play - it would only mean the bearing isn't worn badly enough to cause looseness in the wheel).

You should be able to remove the axles without opening the diff up. If the axles have c-clips or snap rings on the ends inside the diff, you can usually get the axles out by dismounting them from the hubs and getting them free of all attachment except the diff, and then use a large flat-tip screwdriver as a pry bar. Use it right where the axle body mates to the diff, and lever it while you pull/yank/shake/swear at the axle, and you'll manage to pop the axle out of the diff. Sometimes it takes some time and profanity, but so far it's worked for me everytime.

SOURCE: whining/grinding noise at deceleration

If the noise is on decceleration mostly like it is the pinion bearing in the diffrential. Could possibly be spider gears as well.

How would I know if my turbo is not working on my 2006 Ford Focus 2.0L Tdci as the car drives well and has power


Hi mate,

First, remove the exhaust pipe all the way to the turbo, so you can see the turbine wheel. This should look clean, with no carbon build up, scale or oil along the surface, and the blades should be free from cracks, wear and damage.
If the turbine in the turbo wobbles etc, you know it's damaged.

If your car runs at all that means your turbo is working to some degree, as otherwise the car wouldn't start at all.

The link below has a good example.

Have a nice day :)

How do you change the rear wheel bearings


The rear hub and bearing are combined into a single assembly. The bearing is sealed for life and requires no lubrication or attention. If the bearing is worn or damaged, you have to replace the entire hub and bearing assembly:
loosen the rear wheel lug nuts, raise the vehicle, place it on jack stands and remove the rear wheel.
Remove the brake drum or caliper and disc.
Remove the dust cover (in the center).
Unstake the hub retaining nut (bend the part out that locks it), unscrew the nut and remove the thrust washer then remove the hub assembly.
Install the new assembly and thrust washer, tighten the new nut to torque 134 lbs, then stake in the edge of the nut (opposite of unstaking).
Tap the dust cover into place, all around the edge until it's seated.
Reverse removal for the rest.
Hope this helps you understand the process.

Complete loss of boost


Yup your turbo is toast, ive had the same thing happen on a nissan skyline. The smoke you describe is the oil escaping from the turbo core and burning off in the dump pipe.Even though you managed to get the nut back on the compressor wheel the damage to your exhaust wheel, bearings and shaft is already done, chances are you'l be missing a few fins in the exhaust wheel to say the least, it would've propelled itself in the exhuast housing probably spinning at atleast 25,000 rpm.The turbo in the gt4 is a stong unit, just how much boost were you running? :)

I have a supra with a 2jz twin turbo stock an went on dyno it only pulled 129 rw kw i got told my turbos were not working properly and i should be pulling over 200 at the wheels any sugestions what could...


leaking oil

if you pull the intake pipe off (that is the pipe from the throtle body to the turbo) you will be able to tell if there is any chance of leaking oil by running you finger on the inside of the pipe if there is no oil then maybe the turbines have a bit to much play for the full boost preasure if there is a fair bit of oil ten i would say you have a leak you should also be able to tell if it is leaking oil by how much smoke is blown out the exhaust.

hope i was able to help
