Too much gap with Powerflex upper wishbone bushes
Posted: 13 Aug 2026, 15:43
Time to replace the upper bushes came (lasted 10 years ish!) so I opted for the pricey powerflex kit- purple and shiney!
However on carefully pressing in to new upper arms and fitting to the van, I have around a 4mm gap so that the arm can move laterally by this amount. The bolt is tightened up and there is no way to take up the slack, since the bolt tightens against the inner tubing, which sits against the large adjustment washer. I am using the original washers for my van which are in good condition and 4mm thick. Thicker ones would make the problem worse unless I am mistaken.
Has anyone come across this problem? On searching I couldn't find a mention of it. The only solution I can think to make it snug would be to put the inner tube of the powerflex assembly onto a lathe and take the desired amount off the end.
Grateful for any thoughts.
