Having a drivetrain problem. I get a loud clunking noise from the drivetrain when I start and stop. I've brought it in twice. Now they say they can't fix it and I have to live with it. Anyone else having a problem like that?

Did the dealership even explain what the problem is? Warranty won't cover that???

Hey Steverino, I as well had similar conditions on my 02' Escalade. It only has 43000km or 26000 mile's on it. The Dealership checked on several occasions and could not distinguish the problem. After a few months, just last week the Coupler on the front differential blew, spewing differential gold all over my driveway and driver side front rim. Had it towed in and low and behold...I was advised a new front differential was needed. I guess now we know where the problem was and where it was eventually going to lead.

I am not sure if this helps but something to consider having your Local Dealer look at.

Good Luck Steverino

I would take it to a different Cadillac dealer, or phone the Cadillac regional Manager for your area.

I have an '03 Escalade with less than 1000 miles on it and it clunks when it downshifts into low gear. I also get a deep rattle at idle in my dash after the truck has been driven for a while and is warmed up. I think the rattle is related to whatever the problem is with the clunking. Of course the dealer couldn't hear anything! I'm just going to keep taking it in to them until they get tired of seeing me and fix it.

Hi –

I sometimes had this problem, too. What I discovered from other websites is that the transmission sometimes neglects to downshift once you come to a stop. You hit the gas and CLUNK - the trans sences the sudden need to accelerate and finally drops the gearing into first gear, making the clunk and jolt. Now that I’m aware of this, I take my foot slightly off the brakes while at a stop – If the SUV rolls, you know it has engaged first gear. It’s a poor fix to the problem but Cadillac still says that they don’t know what the issue is because they could never duplicate it when I took it in.

Hope this helps.

I have the exact same problem in my ext. It only happens once every couple of months with me. The dealer told me that its the awd system in the escalade and thats the same reason when i change gear into reverse i hear a huge clunk noise (really annoying in underground parking).

I have a 2000 Escalade and the clunk is only when accelerating from start.

The dealership has installed a new driveshaft and yoke but the clunk is still there.

They say it is a computer caused problem because the Engine computer and the Tranny computer are not communicating properly and that Cadillac have no fix for this problem.

My 2000 Yukon XL dis not have this problem , but it had a different rear axle than the Escalade so I am wondering if it is only a problem with axles with rear drum brakes??

Has anyone wrote directly to Cadillac about the problem??


Thanks
John :crybaby: bouncer:

I get it all the time when both the car is one and off. I also get a huge clunk when putting it into reverse and park but GM blamed that on their awd system.

I get the same noise in reverse, and the dealer assured me its nothing more than the shift linkage moving.

Re: Drivetrain problems (clunk)

I just had my Escalade in for other reasons and for the clunk in the driveline. They told me that at this time they had nothing to fix and thats the way they are.
They handed me a service bulletin and it explained the problem.

Service bulletin #99-04-20-002B (08/21/2003)
Info - Driveline clunk

I have not had this problem on my 2003 Escalade. Other people have and savvy dealer service departments know that the computer can be reprogramed to resolve the big downshift clunk. Any time you hammer a drivetrain hard you can break it. I wonder if the big clunk didn't cause the drivetrain failure?

Ihave a 99 escalade and had a clunk taking off from a stop. It ended up being the "slip yoke". It felt like it was from the rear end but it's from the transfer case (I think). They had to re-balance the drive shaft and install new u-joints after installing this piece.
