Bump Feeling when Taking off

**smuesse** · #1 (**permalink**) 04-08-2008, 07:37 PM

Since i bought my truck i have noticed it has bump feeling, its kinda hard to discribe. When i stop at a light, i feel a bump, when i take off i feel a bump. its like something has slack in it and dosnt catch until the truck is moving some. All my U-JOints are fine and my rear end dosnt have any slack. I can move the drive shaft up an down about an inch at the carrier bearing. Im not sure what this is and its very annoying. Could it be a bad carrier bearing? It hasnt gotten worse and it hasnt gotten better. Any ideas?

if you can move the driveshaft up and down that much at the carrier bearing its time to replace it, that should fix your problem.

Your carrier bearing shouldn't move like that its prob the problem

Thats what i was thinking, the nothing is wore out looking at the bearing, it just moved up and down, its surrounded by rubber that looks like its suppsed to move so i was wondering if i should look into replacing it. I hate the two pice drive shaft. I would like to put a solid Drive shaft in it. I dont have time to work on it this week, maybe i can get it fixed next weekend. We are leaving for the Brownsville area after work today.

Does it clunk in the front end ever? Possible ball joints going bad

I did, and found out that it was the ball joints causing that. The front end is all tight now. I had hoped the ball joints were causing that too but they wernt.

Oops missed your statement on the carrier bearing. Yeah I would say thats excessive. Replace the carrier bearing

how did your problem turn out. I have just noticed the same problem.

Yeah, I seem to have that problem, but only sometimes though. I am dreading the ball joint replacements. they are expensive! How much are the carrier bearings?
