Examined my new car today and the wishbone bushes have failed, front and rearward fubar!

So what to do I wondered. I have an old pair here with failed fronts and on examination the rearward bush is not too bad, far better than whats on the car anyway...so order some Polly and re fit, but then I remembered I had BMW m3 bushes said to fit in another thread on here a couple of years ago, in relation to the mark dtm press at newent thread, when we all bought bushes from all German parts and mark pressed them in at newent, until the press broke that is.

Bugger it I thought, nout to loose, I cut the old front bush out by drilling round the rubber to remove the spacer and hack sawing through the outer to remove the whole bush, easy enough...

...now the hard bit, get the new bush in. Put the wishbone in a vice and whaked the bush in with a hammer by tapping (well,belting) round the outer metal edge of the bush! Piece of pess, as they say, and frankly I couldn't believe it went in so easy, although it did need a good belt to get it in square.

Obviously this is not the correct bush for the omega in that the centre hole is not central on this part, it gives a 3.0mill wider track, so the center hole is off set by 1.5mill each side, so begs the question is the outside diameter of the bush a fraction smaller maybe? Might explain the easy fitting.

Anyone know the outside diameter of the correct bush? I know a certain moderator has a set waiting to be pressed in, and if the size shown in the pic below is the same, I'm sure he won't need a press to fit them, just belt them in with a hammer, hopefully?

This pic shows the new bush fitted in the wishbone on the left in the vice, old bush remnants behind, and new bush to go in the wishbone on the right, I'll do that one tomorrow and fit at the weekend just to see how it goes. 
 


In fact it might be worth trying the same procedure on the rear bush as well, ya never know, would be so good if we don't need a press after all...... Maybe?  :-/

I should add, I removed the plastic spacer before hammering the bush in as it would have broken or been damaged. It just levered off and presses back on again.

Sometimes the new bushes go in ok, sometimes they are tight, dependent on manufacturing tolerances I guess.

Rears are easy enough to press in.

TIS does state that the front one can have a wipe of oil around it before fitting but the rear must be fitted dry.

Well, theres always a bigger hammer I guess? SammaAAAAAY 

I only used a claw hammer.  :-/ and the remaining bush does have a different finish on it, so may well be more stubborn.

Which end did you use

The blunt end, as always.

...so anyone got a genuine omega bush they can measure?

[sassanach]

genuine vx bush sat on my desk here measures between 58.05 to 58.55 dia

[feeutfo]

Thanks S.

58.55 might be considerably tighter fit ? 

And .50 of a mill is a lot of variation.... Still, I have a wide range of hammers.  :-/. 

[sassanach]

that was measuring the the same bush in two axis, the mean dia would be 58.25 approx

The sledge should do it, Chris..

Is it not possible to press them in using the vice?   :-/

Possibly,  that was my original plan, but...

The vice jaws in this case don't quite open enough for the width of the wishbone and the bush, plus it really needs a drift to allow the pressure to fall on the bush rim, as the center spacer protrudes. Other wise the centre spacer would be forced off centre. A stress best avoided to my mind?

...and I had a feeling the vice handle would bend or rip the vice off the bench.

Plus the shock of the hammer blow helps considerably this way. I was concerned the bush rim would pean over with the hammer and start the rubber off delaminating, but no, it took it well. In that size anyway.

My concern is some production tolerances or size variation would mean too much of an interference fit, and too big a hammer would then batter the bush rim cussing problems there.

But in this particular case, was amazed how easy they went in. I was expecting a right battle.  8-)

Job well done. a case of ---'Miracles we can do now, the impossible might take a bit longer'
