Thumping on right side

Motor mounts? Tranny mounts? Just some things to check out.

Just returned from another 5 days hunting. I could not get the clunking to return but I have so many squeaks and creaks now it sounds like it is infested with mice...

The clunking from the front right is back. I recently bought a quad and trailer. This week I went to sand lake pulling the trailer, which is pretty light I think, and while going up hill I heard the infamous clunk. I got worse and more often pretty quickly. I did the test with jacking up the front right wheel and turning it while looking at the diff mount and it moves up and down what looks to be an inch. I did the hug and pulled in and out on it to check ball joints and it seems solid. I just crossed 70K on the way back home. Also it makes noise farther back along where the torsion bar mounts when turning right while accelerating or driving over bumpy ground. I know I need to get the cross-member replaced. I have read mixed things about the powertrain warranty covering it since it does directly hold the power train (front diff) in place. I have seen some pay out of pocket and some say it was covered. I don't want to go to the dealer and have to argue just to find out I am wrong. So far I have had good luck with taking it to Vic Alfonso Cadillac, formerly Hummer. Pleas let me know how to approach this with a dealer. And for the other clunk-creek from the torsion bar area, what should I look for and how to test it out. Thank you guys :thumbs:, this forum has always been a good help and source of info.

Here's my opinion (in order of probability)...

Smoked upper ball joint.
Loose shock bolt.
Smoked Crossmember bushing.
Loose steering rack.
Loose skid plate bolts.
Loose body mount bolts.
Dry CV-joint on a half-shaft.

Any advice for dealing with the dealer?

My dealer replaced the crossmember with no issues. It was fairly severely banged up also. I think it just depends on the dealer. It you have a relationship with them they usually work harder to cover things for you. Some of it is how they write it up.

I will call them tomorrow and then let everyone know the results. So far they have been great to deal with and hardly cost me a dime so farr. I am just afraid that they will fix one thing under warranty then find other stuff that HAS to be fixed now that will get expensive. I have seen other people come in there for a mileage service on a Caddy and walk away $2800 poorer.

Pull the svc mgr aside and ask him where he stands. If you dont like the answer, find another dealer.

Just have to know your own powertrain warranty (there are different versions out there, depending on the year) and be able to quote it. For example, crossmembers aren't covered by powertrain warranty but the bushing is? How do they propose to resolve that conundrum?

 

[SGT-Wright]

I call them today and spoke with the Hummer service person and they said no on the warranty, but when I challenged them and gave examples they said they would look up the man hours code and see if it has been billed or warrantied before. They said to call back tomorrow and they would have an answer for me. If they don't cover it then I will just order the crossmember with new improved bushing with lifetime warranty from our fellow forum member. I was also thinking about upgrading to the CI diff up front. Has anyone had problems or grenaded one of those yet. I have the aluminum one and it is still holding up so far, but I have not MOAB'd it yet. I just want to make the front end better and stronger "before" it breaks as I am not a fan of getting stuck with a breakdown on the trail.

Fixed it! It was the body mount bushings. I found the thread that someone else here wrote up about it. I cut out some 1/4" rubber spacers to tighten the gap in the body bushings from settling and wear. I only did the three on each side between the front and rear wheels. The clunking noise is gone now and it only made a couple noises this weekend at Sand Lake when pushing it pretty hard on a few hill climbs in the dunes. I will make more rubber washers for the rest of the bushings soon. Thanks for everyones help. :cheers:
