MY Wagon Vibration

Matt · Post by **Matt** » Mon Mar 12, 2012 9:50 pm

I am chasing some possible causes of a strangle rattle vibration coming from the passengers side of claudia. (aka MY Wagon) I have just replaced the outer cv joint and ball joints. Everything else bushes, rack ends, tie rod ends. wheel bearings, feel good. But i still have a vibration, it isn't really coming through the wheel either. Any suggestions? Was thinking maybe the front diff bearings??

There was a thread about this a few weeks ago, something tells me it was yours too

Anyway, if it was a diff bearing you'd know about it pretty quickly!

My best suggestion is to still replace one shaft at a time with a new one. Mine didn't make any noises but it turned out the shafts would get off balance then oscillate by cancelling each other out then slowing going out of sync until they were both working together to create a vibration that some times would shake the car violently until you slowed down. Corners it would happen quicker due to the wheels rotating at different speeds. A bumpy road was the best to travel down without noticing it. Smooth roads were the worst.

I also found it was the inner joints that had the issue.

Cheers

Been chasing a da doonk in my BWumby for some time and only this arvo went to swap in a nice rack end and found the rack shaft itself has play in the rack housing. It does cause my steering wheel to shimmy a tad, but not a vibration.

Spare rack going in shortly. The da doonk would happen left and right but not when brakes were applied. Has new CV shafts and ball joints 20,000km ago so not thought to be them, suspecting gearbox mounts allowing box to shift a bit but they seem OK just slopy with age.

Matt, you wre asking this one before is it a real shake shudder vibration or real little oscillations annoying the poo out of you?

Bennie beat me, but got another fix - the staked uni joint between your rack (not the one in the blue dress) and the firewall causes a real tricky to track down vibration. I got a spicers hardy one to replace the little uni joint itself.

Can find the part number if you not find it here under search

Sorry i forgot i had the other thread started my bad.

Shaft replacement is that easy on Claudia in fact i can't buy the inner joints anymore or the shafts for that matter

But i will hunt some down eventually. The vibration is more oscillation then a rack, i knwo what a rack end tie rod end vibration usually feels like.

I had a weird vibration once on a MY wagon. It turned out to be the inner CV joints. Someone had fitted 2 new tripod type joints and these were getting out of sync. We fitted new (6 ball race) inners and problem solved.

Got it sorted, ended up the suspension had sagged and made the cv shafts slightly to long, so i switched the the DOJ Bearing around the other way and no more vibration
