I am guessing it is still under the factory warranty. Take it to the dealership and have them fix it for free.

SOURCE: rattling sound in steering (at low speeds)

I sounds like you need to grease the intermediate shaft. GM sells a kit that consists of a plug and a bag of grease for around $18. It has been a few years since I bought it so the price could have went up. They also offer an update shaft for around $100. I am nearly 100% sure this is your problem. I have a 03 Yukon and have done it 3 times in 120,000 miles.

There are a few other posibilities, but they are not so cheap. The next logical problem could be the power steering pump or the valve in the gear box.

SOURCE: power steering problem when turning right

I'm not sure if that truck has rack and pinion steering, or a steering sector. In either case, it sounds like you have stuck valve and the hydraulic pressure is fighting you, instead of helping you. When ever you turn the steering wheel the valve is supposed to move and direct the hydraulic oil pressure to help you steer. The valve is built into the sector or the rack and pinion, you may have to replace the assembly. There are companies that recondition those items so you might want to shop around.

It sounds like your front 4x4 actuator on the front differential has locked up. It's common to happen and the fork that engages the 4X4 in the differential is still locked up or partially locked up.
On the full size, the front actuator is electric, not vacuum.

When in 4wd mode, a switch on top of the transfer case conducts 12 volts out to the actuator. Wire #50 (brown) is the 12v feed, and it conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.

Check voltage at the connector for the front actuator (at the front differential - it looks like a large bullet that threads into the front diff.) If it has 12 volts, the actuator is the problem. If it does not have 12 volts, check the transfer case switch and the power feed to the transfer case.

I'll assume it is the actuator, if the plug to the actuator is getting 12 volts when in 4wd.
The way this actuator works, is it is a sealed chamber that gets heated by voltage. When it heats, the pin in the end swells and pushes a shift fork in the front differential. The shift fork engages a spline on the passenger side of the differential, and boom! you have 4WD.

GM offered an upgrade to this actuator that is a motor instead of a heated device. However, it requires a small harness addition, a spacer, and a new actuator. It is about a $150 to $200 option.

If I were you, I would buy a new heated actuator. They are available at most auto parts stores, and are about $90. They are also on eBay for about $55 plus shipping. These are very easy to change - just thread out the old one, and thread in a new one.

Good luck. The actuator is usually the problem 90% of time but recheck all of the wire harness just to maker sure there is no short before replacing any parts.

I'm looking to replace the rear axle on my 1997 4 door 4x4 GMC Yukon 3.73 gears would a rear axle from a 1998 Yukon 4door 4x4 with 3.73 gears bolt directly to my 1997 Yukon


yes
the housings will be the same
clue here --if the diff center comes into the housing from the front not a problem
if it comes in from the rear ( tin cover removed ) replace the complete housing as you will have to have expertise in resetting the bearing pre-loads for the diff center bearings

Knocking noise on driver side font on 2005 Yukon.


hello,
with out more info it sounds like it could be the drive axle could be going bad if it's a 4x4 or possibly one of the pins holding the brake caliper in place has backed out and rubbing the inside of the wheel. I would also check the wheel bearings to make sure the wheel is not loose and making the noise you hear.

I have a 1996 Yukon 4x4 & just recently I get a humming/vibration effect at 60+ mph. I had a front wheel bearing/hub assembly replaced, 2 new tires, rear differential refill & it still does it. HELP!


The best way to determine where noises are coming from is to use what are called chassis ears. They are basically microphones that clamp to suspect components and are connected to a switch with headphones so that you can listen to specific components. http://www.tooldiscounter.com/ItemDisplay.cfm?lookup=STE6600&source=froogle&kw=STE6600 You can spend a ton of money replacing parts until noises go away. Hope this helps.

There is a horrible rattling noise in the front end of our 03 gmc yukon xl. i think the 4wd linkage is broken.


It sounds more like a possibly bad CV joint in an axle shaft or internal differential problem. There is no mechanical linkage to the front axle, its all electronically controlled. The front suspension is pretty good there aren't a lot of rattle type noises created from it. I need more info to diagnose better. Does it do it only moving? or stopped? over bumps only? in 4wd only? while turning? certain gears or speed only?

My 1996 GMC Yukon 4x4 transmission will only drive in 1st and 2nd


It will take off from a stop in overdrive but as soon as it shifts into 3rd at about 30 miles per hour it jumps into neutral? If yes, you have a burnt 3/4 clutch. The transmission will need rebulit. Cost of about 1600 dollars.

I just fixed a friend of mines 96 yukon...shift to neutral press 4H and u can hear the actuator make noise (we even replaced it with a new one his idea and the same thing happen as old one), so as he hit the switch for 4H i layed under it (on 4 jack stands) and I could hear the motor on the transfer case make a loud noise (well thats working) and before all this I asked him did u check all your fuses (he said guarnteed to be all good) one night it was bothering me so i looked through the owner manual for the yukon and in the fuse box on driver side by the door there are (2) fuse for the 4wheel drive unit,pull one of the fuses good...pulled the other one and it was blown put in a new fuse and it works like brand new..pull fuse for anything that has to do with 4 wheel drive componants,
