 Hi All. Is it ok to re-use the wishbone mounting bolts. I think most people do and new ones seem awkward to get hold of.
 I have some time before doing the job, so could order some from the dealer. Using the old ones would be handy, but they are safety critical items.
 Cheers.

They should really be replaced but very rarely is it actually done

Lemforder come with new bolts

Are you on commission?

Hit and miss....some do and some dont.

No problems with re-suing the old ones though.

Note: Lemforder wishbone bushes seem to last about 2 years.....

Can't see them being Genuine ones then like so many people keep saying as The Genuine ones last years

I suspect they are.....I wonder if the roads are getting worse or a tired suspecion setup takes more out fo them.

Thanks for replies. Cannot see that the 2 litre will put them under too much stress anyway.

As did my egay cheapies last time, hence fitting them again this time. Be interesting to see if these ones last 2 years too... That'll be just over 4 years and still not spent as much as Lemforder ones

That said, I wouldn't want to be paying someone to fit them every time

[andyc]

I would say use new bolts as the old ones will already have been stretched

Front Bolts 90468500 £2.75 each
back Bolts 90468501 £2.42 each
Nuts for above 90538056 £2.11 each
Ball Joint to Knuckle Bolt 90496191 £0.94
Nut for above 90538057 £0.94 each

To be honest Andy, the bolts on the wishbones are not torqued up high enough to stretch them.

You certainly dont feel them stretch like the head bolts and subframe bolts.

As they are torqued to 120 Nm then angle tightened by 30° then by 15° surely by definition they have been "stretched" and should be replaced??

The "book of lies" certainly says so, and I was always taught that ANY angle tightened bolt should be replaced ??

Try doing a head bolt or subframe bolt....you can tell very obviously when they stretch 

These just go tight.

No need to replace.

Consider also that the angle fit method is used on many fixings these days and not just stretch bolts

[Liam]

As DTM says, angle tightening doesn't necessarily imply yield tightening (stretching). Angle tightening is just a method of achieveing more accurate control over the final tension. A tightened-to-yield fitting will always use angle tightening because accuracy is important, but so might a critical non yield tightened fiting - omega wishbones for example. Also front calipers are angle tightened I noticed recently, whilst re-using the bolts

[feeutfo]

Just to add, as we have the torque procedure down, that the bolts should be tightened with wheels loaded/at the correct ride hight. Not wheels hanging while jacked.
