I find it a right pain in the arse torquing those bolts up with the car on the ground and no pit, so what I do is leave the car in the air, and with the lower ball joint still disconnected, pull the strut out the way, and shove the wishbone up behind it. Jack to hold it in place. Can just about get it to the same angle it would be with the car on the ground, and you have much more room to get your torque wrench/bar/foot undeneath. :y

Lemforder come with new bolts  :y
The pair that I bought from AllGerman last week each came with two large nuts and a smaller nut & bolt (I'm guessing that the bolt is a replacement for the pinch-bolt on the lower knuckle  :-/)

Taken the day off to fit them today so hoping the rain will hold off :y

Yeah my recent Lemforders also came with nuts for the main bolts (should be replaced as they are an ovalised locking nut) and a new pinch bolt and nut.

It is indeed a pita, however it's important to the point that vx load the suspension to simulate the drivers weight in order to set the best average ride hight before setting the bush center spacer position by tightening correctly to specified torque.

I believe Mark tightens as much as possible wheels loaded, then re jacks to tighten to the final increment. Provided the centre spacer does not slip back round that's good enough. Or if ramps can be used that would help if they ever clear the bumper of course.

Yes, as tight as possible on the ground and then jack up for the final torqueing up

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.
I guess it would be interesting to see how long the ones on the MV6 last.

For info, MDTM and I rebushed them 2yrs ago (before Newent that year, where his press got, err, 'heavily modified ;D) with genuine GM bushes from a dealer.

Got the new wishbones fitted.

Before starting I measured the amount of camber using a roofers square and a length of metal channel under the front wheels to give a datum. After several remeasures I found that I was getting a repeatable 15mm (2deg00') on the N/S and 21mm (2deg50') on the O/S.

I was hoping that after fitting the new wishbones the camber would correct itself but I now have 13mm (1deg45') on the N/S and 20mm (2deg40') on the O/S.

Tomorrows task will be to adjust it myself. Now I have found a repeatable way of measuring the camber the worst I can do is return it to 'as found'.  :y

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

Why?

They're not stretch bolts.
I would like to replace any locking nuts, but spring washers would work just as well. (You're only supposed to use a nylon locking nut once, unless Omega uses a Philidas type?)

Doing mine tomorrow - and not really looking forward to it!

Best you can is all you can do without a previously correct measurement, although if the conversion to degrees is accurate can 1.degree 10 be set?

Bear in mind that adjustment of the camber (and even just swapping wishbones) with throw out the toe setting as well. :y

FWIW when i did my wishbones I got them from the local VX dealer.  They didn't offer bolts so I had to ask for them and they had none in stock.  Rolled eyes at the prospect of ordering and said they don't use new.  This at a time when a pair of wishbones was on special offer so lots in stock.

I used the old ones as a direct result.
