#99 of 172 Re: REAR END CLUNK/GRUNT by nsauceman Jan 08, 2008 (8:19 pm)
Replying to: mule2 (Oct 18, 2007 4:55 pm) I took my GMC (2001 extended 4x4) to the dealership about the clunking issue and it cost me $400 to get it fixed. I let it go for quite a while and it started sounding worse and the "bump" you feel started getting worse as well.   Seems to me that GMC would have a recall about this problem as the last 2001 truck I had did this as well except I did not get it fixed then. Back then I don't think they really knew a lot about this issue but they sure did this time. Just as soon as I said what it was doing they knew exactly what it was doing. I did not even get out of the parking lot with the mechanic before he said for me to head back to the doors.   Does anyone know if there was a recall and now it has expired or anything relating to this?   Thanks Replies to this message: brian04 (Apr 11, 2008 8:31 am) gmcman815 (Jul 12, 2008 9:13 am)

Replying to: clarkston (Jan 08, 2008 8:03 am) darkston, I have an '07 Classic Ext Cab W/T. I installed a pair of Westin tubes and noticed a vibration at 35MPH. I took it to the Chevy dealer and they said it was the tubes causing it. I have to keep the step tubes so the wife can get in the thing. BTW.....no creaking noise.

New to the forum and have a problem that I thought other may have experienced. I have a severe exhaust vibration that occurs when idling at a stop light (not during exceleration) and while maintaining a constant speed. Just finished my second visit to the dealer and still no improvements. Dealer is saying that GM is aware of the problem but are just considering this the "nature of the beast" with the V6 it comes equipped with. Dealer also stated that they are aware of this problem and have tried several different things (including flex hose) but have nothing. Any ideas??

#102 of 172 02 Sierra Rear End Noise by qwikmalibu Jan 10, 2008 (5:27 am)
I have a 2002 Sierra K1500 4x4. High mileage, but very clean and well taken care of.   I just recently noticed a low speed (30 or less mph) noise when coasting or braking to a stop.   The noise is coming from the right rear (Had a brave passenger lean out and listen).   I replaced the brakes and rotors nearly 1 year ago. I also completely removed the parking brake shoes and adjusters from both sides to see if that was the source of the noise. Since that didn't do it, I took both rear rotors off and inspected the backing plates to make sure they were not making contact with the rotor. Then I swapped the rear rotors and the noise was still on the right side.   I put the vehicle on a 2 post lift, placed it in gear, and with a rag in hand, applied drag to the right rear by pressing on the inside sidewall. I was able to recreate the noise. So, I replaced the right rear wheel bearing and seal. I noticed the C-Clip was wearing more toward the outer diameter on the side that faced the side gear, so I put it back in facing the other way to start fresh and reduce lateral movement of the axle.   The noise is still there and I am getting desperate.   Has anybody else had experience with this elusive noise?   Thanks in advance.

Replying to: xbbuster (Jan 09, 2008 5:51 am) I checked the westin website they reccomend 74 foot lbs torque for the tubes not sure if the installer did this, seems to me they just used a impact wrench, never did see them torque anything, BTW my wife needs those steps too.......

Replying to: gumpp08 (Apr 17, 2006 5:08 pm) Look at your exhaust manifold bolts and make sure they're not broke. I have a 2000 chevy that sounds like i lifter noise but its actually the rear manifold bolt is broke.

Replying to: xbbuster (Jan 09, 2008 5:51 am) Try talking to the dealer about the GM mobility program, if you or any of your family members have a problem getting in or out of the truck, and you can get a doctor's slip stating this , they will pay up to $1000.00 to install steps or a lift. I had running boards installed on my silverado when I bought it, and GM paid for everything. I am looking for a new truck now, and I asked the dealer if they still have the program,and he said they did. my wife has implants in both knees,and she has trouble lifting her leg high enough to get in I hope this helps. maybe they can install anew set of bars.
#106 of 172 2007 Silverado 2500HD clunking noise and other problems by 07liftedbeast Jan 13, 2008 (9:01 am)
i recently purchsed a brand new body style silverado 4/28/07. i then waited about 2 months and noticed that when ever I hit a bump going like 5-15 miles per hour there is a VERY noticeable clunking noise coming from the rear end... didnt think much of it till it started getting worse... i now have a 6" lift and 35s on the truck, the clunking is the same it was after 3 months... im gonna be taking my truck into the dealer on monday for my hindges that are rough when closing the driver door, and the same as some other people the side steps. i ordered OEM running boards and put them on and now theres a creaking noise coming from the door... only when the doors are closed though... im not happy with the vehicle that i decided to purchase... im a big chevrolet fan but the last thing i need is for GM to tell me to wait and then have my whole rear end fall out going down route 28, or to have my driver door to fall of, or even have my running boards snap on me... as far as the rear end goes i thought it was a chevrolet thing.. then i see al these other posts about it and how they had to pay $400 to get it fixed... my truck only has 6,500 miles on her. i dont feel i should have to pay anything...

Hey, After looking at westins website, I found that there is a one eight inch minimum clearance on the front body pocket mounts for the steps bracket, sure enough the installer did not follow this in the instructions for installing the tubes, I crawled under the truck the other day and loosend the steps and adjusted to specs, Then torqued to 74 foot pounds, and Voila no more creeks or noise.........Why did i pay someone to install these..........Damn
