Wondering how long the shocks, rear pinion seal/shaft, and fronts struts should last on this vehicle? I have 83,000kms which are all to and from my 3 kids sports. I tow a tandem jet ski trailer on occasion. I took it in to the dealership for it's semi annual servicing, and have the brakes done(told back in June that they would need to be done this fall) and was absolutely horrified to find out that apparently my shocks were cracked and leaking and needed to be replaced. They also said that the rear pinion seal was leaking. A $2.75 part cost $240. in labour! My total bill by the time everything was fixed, $2600. I've only had this vehicle for 3 1/2 years! I phoned GM and the service person said she would look into this and get back to me, but never has. This vehicle has been in for recalls, and warranty work since the day I got it, on a very regular basis, and as much as I love it, I'm really getting fed up. ? Hopefully someone can enlighten me on the life expectancy on shocks. Replies to this message: rsht (Nov 14, 2009 5:51 pm) boatergal (Nov 20, 2009 8:52 am)

Replying to: gmni32 (Nov 13, 2009 2:47 pm) The humming sound is coming from your on-board compressor, a part of your auto leveling system. You are absolutely correct. The compressor should turn ON for several seconds when the ignition is turned on or started your engine. Unless the load to your vehicle increases, otherwise, in my case, I have not observed/noticed it ever comes on again until the next time I turned the ignition on. If your on-board compressor turns-on/off every so often when the ignition remained on or engine running without any increase to the load, then that may be a sign of a leak in the auto leveling system. The compressor is most likely located behind the driver-side rear wheel wall, mounted on the outer side of the H frame, there should be a shield around the compressor to keep most of the road debris away from the compressor as well as keeping certain amount of the humming noise within... check to make sure the shield is not coming apart/off...

Replying to: boatergal (Nov 04, 2009 9:23 am) How long shocks/struts last, that in my opinion depend on a combination of driving style, road conditions and how much load you carry using your vehicle... As far as the pinion seal, I have seen some lasted the live of a vehicle, while some with minor sippage (i.e. wet appearance around the outer seal area), and for some unlucky owners had to replace the seal within 10K miles. Double check with your dealership, I thought with the exception of tires, brakes, shocks, otherwise, the pinion seal may be covered under the powertrain warranty for 7 years or so...???

Has anyone removed the compressor and shocks and installed shocks from a non-autoride Yukon/Suburban. Will this work.

Replying to: rsht (Nov 14, 2009 5:51 pm) I had the work done at the dealership, and I even phoned GM Canada directly, and both said that the repairs were not part of the warranty. Thanks for your reply.

Has anyone converted the autoride on a Yukon XL to convertional style shocks? If so what shocks did you use? Thanks Replies to this message: rsht (Nov 21, 2009 2:30 am)

Replying to: jim334 (Nov 20, 2009 7:27 pm) I have not done it before, but I have heard and also seen it done before (on a TV program call Trucks on the PowerblockTV.com). If I recall correctly, the replacement gas charged shocks were by Bilstein, and the kits comes with some sort of plug to fake the OEM circuit from displaying an error message all the time on your dash. I tried to find that episode, but I was not successful, Sorry. Just in case, in that episode, they were replacing the OEM autoride system on a 2007 White colored Tahoe/Yukon...   http://www.powerblocktv.com/site3/index.php/trucks
