Poly bush pins
Lightning - 6/2/09 at 10:02 PM

The metal pins through which the bolts pass, are they normally just mild steel? The wishbones on mine were extremely stiff and after removal and cleaning of the bones I removed the pins(sockets- whatever you call them). There were very corroded and would only move with lost of hammer persuation. These will have to be changed. New ones will also be greased.

The Bushes? (steel bit in the picture).
I think they are normally stainless steel

They're normally referred to as crush tubes. They should be SS but cheapo's might make them from MS....

Be careful suggesting greasing crush tubes on here. Some people have a phobia over copper-slipped crush tubes and insist you need special silicon grease. Don't tell my car... 3 years and no sign of problems with copper slipped crush tubes.....

Thats what I thought. The bushes seem ok. Ill measure the tubes with a mic tomorrow. Where would be the best place to get these? Or just get tube and cut it up I suppose??

You normally get them with new bushes.
Try rally design, they might sell you some if you know the dimensions (and sachets of the correct grease).

PRobably teaching you to suck eggs but if you're buying new crush tubes then make sure they're a good tight fit. They should still be able to rotate in the bush (with the weight of the car) but have no movement otherwise. And cutting them to the right length is important too....
But I'm gonna be careful there as don't want to open a can of worms!


My MK ones were mild steel.
I used Moly grease on mine as recommended by Rorty.
If it's good enough for him it's good enough for me. A huge pot of it wasn't expensive from the motor factors.

Just dont get it on your nice clothes. Walked through the utility room from the garage and passed through the washing line... my Mum's white top has never been the same!


Hope that helps,
James

Might be worth doing a search on here as crush tubes have been covered several times? The arms on my car were tight due to the crush tubes being too short. If you have the arms off the car place the assembled arm in a vice so that the crush tube is nipped. The arm should rotate freely around crush tube. Lubricated mine with rubber grease.

Greasing them is fine, but using an anti-seize compound in lieu of a lubricating compound doesn't make sense?

i used teflon grease on mine as per instructions from MEV, you can get it in halfords for about 3 gold coins

just to makes sure i have this right in my own head...

with the bolts on the wishbones done up tight the suspension brackets should hold the crush tube tight so it doesn't move and the poly bush should move with the arms around the tube???

Correct, the bolt should not be the pivot.
