uprated wishbone bushes pt2

[JShadzi at aol.com]

Alan, I understand, I have  2B bushings that are shaped exactly like yours, but a tight interference fit prevents fore and aft movement.  I think you may need to increase the interference fit, there should not be any movement of the control arm sleeve relative to the bushing with the proper interference fit.

One problem you may likely be running into...simply making the plastic the same size as the metal sleeve will not ensure a proper interference fit.  Plastic can compress much more than a metal sleeve, you will need to oversize the plastic relative to the metal sleeve to ensure an interference fit that can prevent lateral movement.

<< sorry, i think you misunderstand....  the bushes look like this, they are
tob hat shaped with a parrallel bore through the centre. the outer is a
press fit into the wishbone and does not move.  the centre sleeve is a good
running fit inside the bush, the sleeve is also a good push fit into the
subframe.  the acetal bushes, much like the oem rubber ones, do not cover
the complete length of the centre sleeve, therefore the wishbone can move
freely (relatively) backwards and forwards, this movement was originally
retained by the bonding of the centre sleeve to the rubber bush in the oem
item, essentially the movement has always been there, just controlled.
these items were made to dims from the list, although specified as urq
items. so i am wondering how that movement was controlled in that situation
(maybe the larger diameter on the top hat ran against thesubframe to retain
movement).

> Alan, the problem you have is that you did not make the bushings with an
interference fit, they must press into the a-arm as did the stock
bushings...the stock rubber bushings do no "dampen" anything, there is
really no movement front to rear except for the deflection in the rubber.
