40 MPH shake with new axle on Uplander
RacinBob last edited by
I just had the drivers FWD axle replaced in the uplander and there is a small but noticeable drivetrain vibration at 40 mph when under acceleration. It does not seem to show when not under load so I suspected it was an axle problem.
I jacked the car up and saw a wobble in that CV joint boot when in gear and running in the air. The other side boot rolls true. I am not sure if the wobble was the joint itself or if it was a boot that was not pressed on evenly because because I didn't want to spend a lot of time under the van because of the sketchy safety of laying under a van on jack stands while the engine is running and in gear.
All I could think of is that the axle could be bent. Any other ideas?

@RacinBob Sounds like you probably just got a crappy part. Guess the shop will have to replace it again (they should warranty their work)

Aftermarket CV axle?
Vibration on acceleration/under load is usually from worn or crappy machined inner joints on a CV axle.

@RacinBob If it's a reman or an aftermarket, I've never had any luck with them - at least in a Volvo.

@RacinBob I've seen this problem before getting a bad reman CV axle. It was swapped out with another reman axle that solved problem. Because it was a warranty exchange, I didn't open up the bad axle to see what was going on, but I'd guess there was some crappy machining on the joint.
I also once got a reman axle that turned out to be about 1/2" shorter than it was supposed to. I didn't notice on installation, but I figured it out later comparing it to the old part after it popped out of the transmission at interstate speeds.

@Sovande I've never had a problem with O'Reilly reman axles, only warrantied the short one for my Golf three times. Cheap aftermarket replacement parts are always fine all the time.

@ITA97 Thanks guys, I had not thought about the inner CV being the problem.
Yes it was a reman axle installed by my buddy's shop. I expect they will treat me right, I was asking trying to understand what was the cause. The inner CV makes perfect sense to me,
Unfortunately, I was proactively replacing that wheel bearing as the other front one had just failed at 130,000 miles, The could not get the outer CV out of the hub due to rust and finally just replaced the whole assembly, The Axle that they took out was like new and had no issues.

I hate unintended consequences like that.
