Aurion "wobble"

[Guy ZR6]

Hi all,

Last weekend I became the proud owner of an Aurion zr6 2008. Looks great and the engine and trans seem to be in good condition. It has 220,000km on the clock. 

It does have one issue though that's bugging me. It has a slight wobble... All the time. It's not coming through the steering and the rate or wobble is directly proportionate to the speed of the car.

I had brand new wheels and tyres put on the day I bought it. They were balanced and aligned. 

I haven't taken it to my mechanic yet but I will be this week. Hoping to get some advice from the community before I do as I'm not mechanically minded. 

My friend thinks it's the left rear trailing arm bushing 🤷🏻‍♂️ sounds plausible.

Cheers.

Did you find the cause of the wobble?

I have been having this same issue which has gradually become worse.  I have replaced the drive shafts and motor mounts, all bushes and front shocks, wheel balance and alignment.

I have dropped my trans oil today and found some grey residue so I'm thinking it maybe a failing transmission.

Did U try rotating the wheels front to back? Bulging deformed tyres isn't uncommon with a 200kw front wheel drive

Maybe unrelated, but check  how many turns are on those wheel nuts. These cars have studs that are too short for aftermarket wheels which use acorn nuts. Minimum of 8 turns for a 12mm stud is considered safe. Also check if correct size hub ring is fitted to the back of the rim

Interested in the outcome re. the wobble.

I had a wobble recently and turned out I had RH CV inner boot that had leached out the grease (remaining grease was liquified). Replaced and wobble completely gone. Probably not your issue if you have replace both shafts. 

My 2010 has 165K on her so keen on any preventative maintenance etc.
