Front Tires Wear inside Area
« on: 20 July 2018, 10:54:16 »
Hello

Aligned four wheels about two years ago when new tires installed. Now I can see that inside area wears more than outside in front. Is this typical for V6 Omega or can this be a wishbone case which is not seen in alignment process?

Normally you should get slightly more outside edge wear. It sounds to me like you have excessive camber at the front.

Most of the alignment machines have wide tolerances for front camber so it gets neglected by alignment shops. It needs to be set for no more than about -1o10' for even tyre wear.

Thanks for comments, yes Camber exists, I think I can even "see" it. I will change front shocks soon (and springs, top mounts etc.) and will go to 4 wheel alignment. When everything is open I could probably check the wishbone bushing problem, too? Can this be done just by shaking them, by hands??

It would be best to inspect the bushes. In fact, I'd get a set (or a new set of wishbones) and change them as a matter of course if it's coming apart to change the shock absorbers. That way, you only have to pay for it to be set up once, and you know everything is good.

Seconded. Best practive/OOF advice is to redo the whole suspension in one go. Seems expensive/wasteful but it really is actually the cheapest way of doing it, because you're talking about parts that will all wear out eventually.

Thanks for good advise to change everything at the same time.

I bought this car in 2004 (model 2001) driven that time only 50 000 km! So I know that everything in front is original (except dog bones). Now driven 265000 km so perhaps time to do something. This means that all bushing & ball joints can be worn. New wishbones include all these spares so question is where to buy wishbones with good quality spares. Is the original part the only choice? What is price level of it? I found one "cheap" store here in Finland selling wishbones equipped with bushing and ball joint 89 euro/pc. Can this be good quality? Please recommend, I was thinking that changing all three parts to both wishbones takes time and they also cost something. Press is available so changing bushing is not a problem but to get the whole part (wishbone) is interesting...

Good to hear, already ordered.

How about the bolts of wishbones. How to open after 17 years. Do they have nuts or thread in subframe? Is it better to order new bolts beforehand?

I'd ring the dealer and see if they're still available.

To get the old ones out, get the car nice and high in the air, secure and solid, then use the biggest bar you can get your hands on.

OK, bars available but are there nuts in the other end or thread inside somewhere, I mean if bolts snap?

Nuts and bolts. The nut is the lower part of the vertical assy. You need to get a spanner/box on the top of the bolt to counter hold as you undo the nut. On a RHD car the off side is reasonably accessible, but the nearside bolt head is obscured by the ABS unit. Dunno about LHD cars.

And once the nut is off, try not to drop the bolt inside the sub-frame. Hours of fun fishing for it afterwards if you do.

I wouldn't worry too much about replacing any of the wishbone mounting nuts or bolts.


It is worth using some copperslip on them where they sit in the bushes, but that's best practice for this sort of job anyway.

Thanks LC0112G and Nick W for tips and link. Good to hear that both bolts and nuts exist. I do not like threads in frames.
