Clive Posted May 21, 2022 Share Posted May 21, 2022 There is no bottom ball joint. At the front it is a ball joint at the top, at the bottom you have a trunnion. The vertical link has a screw thread at th bottom, which screws into a brass trunnion, with the thread acting as the pivot for left/right. Up/down movement is catered for with a bolt and bushes through the lower wishbone. The trunnions should be OILED (not greased) with ep90 (or 80, or 80/90) gearbox/diff oil. The nipple is an inch or so above the trunnion on the vertical link Quote Link to comment Share on other sites More sharing options...
standardthread Posted May 21, 2022 Share Posted May 21, 2022 Don't Canely do an upgrade for the bottom trunnion, which, from memory is a ball type joint and sealed for life. Often forgotten or not mentioned is to make sure the EP90 is safe to use for yellow metal (bronze, brass etc.) or it could destroy the bearings etc. Quote Link to comment Share on other sites More sharing options...

Not much more than buying new std uprights/trunnions/bushes. £344.50 to be precise. Trunnions £22.50 each, std VLs £105 each. £5.50. Total £266. So trunnionless about 20% extra. Worthwhile? it depends! 1 Quote Link to comment Share on other sites More sharing options...
