Propshaft centre bearing

[corriepups]

Does anyone know how much lateral movement is normal when pushing/pulling propshaft at centre bearing? Getting dug dug dug sometimes at low speed and suspect bearing on way out

I'm going out on a limb here, CP, and say zero or close to it. When mine went out on my '04 CTT it first felt and sounded like a flat tire while driving. Then a day or two later it started making a banging sound under the center console. It goes bad really fast. So don't wait for that wobble to turn to sudden death...it will. What year is your rig?

Totally agree -- the hand-torque tolerance should be zero flex. Your shaft needs to be replaced. Happened to me earlier this year. Like yours it stared with a subtle noise and then progressed to the thumping in the center console. Classic symptoms. Lots of great info on this issue here in this forum.

Once mine was replaced crawled under the car and the new shaft was very solid, no flex when pushed by hand.

I'm currently in the same boat. Cardan (drive) shaft needs to be replaced. I've purchased a rebuilt shaft from Vertex Auto, as I've heard that their shafts have a stronger center bearing and are less likely to fail (again) in the future. Cost was approx $200 cheaper than OEM, as Vertex offers a core return incentive. ie: send your failed shaft back to them for a $350 rebate.

My current problem is the installation. I've received an estimate for $600 to R&R the shaft, labor only. Other forum members advise that this figure is extreme and that the DIY is relatively easy. I don't have the tools and am sure I'll be hiring the job done; I just don't wanna get ripped off.

Anyone know what the book lists for labor hours to R&R this part (1.5? 2.0?)

Thanks!

Book time is 130 TU or about 1.33 hours.

Thanks for that guys, My car is 04 Cayenne S, 60k miles, I can fairly easily move shaft about 1/4inch up and down so guess bearing is knackered!

My center bearing will move about as much as you have described and the dealer said it was in great shape when my front differential was replaced. Don't forget that bearing is surrounded by a pretty thick rubber grommet for noise isolation.

IMO there should be some movement otherwise the rubber would be too hard and transmit too much noise to the chassis. Hope that helps.

By the time is does the thump thump dance its only a matter of a SHORT period of time before your max will be 20mph on the way to the shop. I speak from experience ugh !
