Title: Use new bolts/nuts when replacing wishbones?
Post by: Thingymabob on 20 July 2012, 14:32:24

Is it advisable to replace any bolts and/or nuts when replacing the wishbones or can the old ones be reused?

I think the official line is that they should be replaced, but in practice everyone re-uses them and we haven't seen any issues with doing so.

OK thanks, then I'll aim to reuse the old ones.
If any of them looks to shaggy, I´ll get a new one.

Does anyone by chance know the GM numbers and/or dimensions for the parts we're talking about? ???

Thanks a lot :)

Just to make sure I get it right; 1+1 bolt and 2 nuts, that´s what keep one wishbone in place, no other bolts or nuts needed? :-\

Depending on the state of/and how much damage you do to it ... you MAY need to replace the pinch bolt on the ball joint, but these are pretty standard nuts/bolts.

When you remove the old wishbone .. make a note of which bolt is vertical and which is horizontal .. they are different lengths ..... when I did the old 2.5 the first time I spent a long while fighting to get the vertical one in  (it can be tricky) only to find I'd put the wrong one in !!!  that resulted in about £5 straight in the swear box believe me !!! ... I now label the bolts with a bit of masking tape after removal !!!  :)

Lemforder wb's come with the pinch nut and bolt. They seem to suffer more with rust and are 100nm tight. They take more of a hammering for the relative size perhaps, so as Entwood says really ... :y

Thanks for all your tips; it's now plain as a pikestaff :y

If anyone is interested, I found this information in the "Opel and Vauxhall genuine OEM parts and accessories catalog"
http://opeloem.com/opel/omega_b_1994_2003/front_axle_and_suspension/front_suspension_arm.html (http://opeloem.com/opel/omega_b_1994_2003/front_axle_and_suspension/front_suspension_arm.html)
This illustrates very clearly what it looks like and which parts are involved.
