Thread: 130 wiggle at speed

I had a wobble looked at recently, a combination of wheel balance and panhard rod bushes had me sorted.

Easy one to look at, make sure the rear springs are seated in top bracket properly. If aftermarket shocks are fitted they maybe a little longer than normal, the spring can fail to stay seated when you lift one wheel. Upsets the balance of the vehicle noticeably. I have Terrafirma shocks on the rear, they do this quite often, a fix is on the list.
Unfortunately the worst front end wiggle, and recurring shudder I had was caused by the disintegrating front diff. (Quite possibly caused by the dealer checking my brake complaints by running the vehicle on stands and slamming the brakes on.)
Whatever it is, get it sorted while they still want to talk to you...

If there's no play in the steering wheel while the vibration is happening could it still be the steering box?

Yes, but it could also be combined with what all the other posters have said and all together cause the problem.
The steering box is the easiest to check and fix, look for any signs of movement on the chassis and brackets and check with a spanner if the nuts and bolts are tight, if so, move on to the next probable culprit, good luck, Regards Frank.

Thanks Frank, I'll check that out first - particularly if it's the easiest fix. Looks like i've got a fun weekend ahead of me!

The dealer has said that in his opinion there's nothing wrong with it and I'll have to pin point the problem area for him to look at. If he agrees there's a problem he'll fix it. Sounds like it could get messy...

Hi All,

Sorry for the bump. Just following this one up with a (hopeful) conclusion.

Jumped under and checked all that you guys suggested and there didn't seem to be much play in any of the componentry. Gave up in the end and took it into Ritter's for them to check out.

They said that the tyres are scalloped but there's no issue with the suspension, the rear axel is completely worn and they also picked up a problem with the diff.

Unfortunately, none of this is covered by warranty. Tyres aren't covered full stop and the car is still safe, drivable and roadworthy with no major mechanical failings.

So I'm getting myself some new Mickey Thompson Tyres and rims for Christmas (currently running with tubes and wanted to make the switch to tubeless) and will deal with the rear axel and diff at the major service in April.

Cheers and thanks for all of your help,
Michael

Tyres can have a significant impact on wobble / vibration issues as well. SWMBO has a Wrangler that was developing the famed Jeep death wobbles. Tightening up the front suspension improved things but the fix was getting rid if the factory tyres. 100,000KM later and no problems at all.

Looks like I spoke too soon!

Issue with the new Wolf rims, same problem is back again hopefully sorted before Christmas...
