Carrier bearing question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

DanoDMano · 04-13-2003, 11:28 PM

I havent posted in awhile, been doing some crown moulding
and painting for the wife.Then I am getting back to my truck!!!

Question:
Since owning my truck, I have replaced the carrier bearing twice in less than a year. Why is our driveline in two pieces and not a one piece shaft?? I think it is bad again but I am not sure yet. When I step on it, or when I let off the gas pedal quickly, I hear and feel a clunk under my feet?

I climbed under and grabbed it and gave it a yank, but I didnt notice anything really loose?

Can we buy a one peice shaft for our trucks so I can quit having to drop my driveline every other month??

Thanks, Dan

Most drive shaft places will not make a shaft over 6 feet long. They become difficult to make and keep therem straight after that length. You can get it done, but it will cost quite a bit.

Thanks longhornmail! Is there anyone out there that makes a
heavy duty carrier bearing for our trucks?

I though I saw a post a few months back talking about an aftermarket bearing.

Hmmm, maybe I need to search..

It actually sounds like somethign isn't right with your truck.
I find the main thing to kill them is one of two things, wither your angles are not right, or the 2 shafts are not slipping the way they should on the splines.
Mine was binding so bad it took 2 of us 2 1/2 hrs with a torch and a BFH to take it apart.

Is your truck lowered? If so do you have an adjustable panhard bar? When you raise or lower a coil spring truck the rear diff will shift off center and will also move back or forward. This will puts a strain on the carrier bearing. An adjustable panhard will allow you to center the diff but will not help the back or forward pressure the only way to relieve this is with a rear slip joint. Also I'm the one that posted about the aftermarket carrier bearing check out this post: carrier bearing

Yeah that is the bearing Neon Thanks!! Have you used it?

I did lower my truck a little with lowering springs and shocks.
Only 2-3" though.

Are the adjustable panhard bars easy to come by? Also how
do you adjust one properly??

I have been brainstorming and am wondering if maybe I have
a loose tranny crossmember, or possibly a bolt loose on the torque convertor?? Would these things also cause a clunk??
