patricklaw7 Posted February 16, 2021 Share Posted February 16, 2021 Hi all,Does anyone know where I can source a rear shock mount polyurethane bush for a live axle Seven? The damper shaft diameter is 7/8" (~11mm). Superflex has one that is almost a perfect fit except the ID of the bush is 12mm which gives a bit of free play (they used to make one with the same part number but the ID was 11mm).Thanks,Patrick Link to comment Share on other sites More sharing options...
7 wonders of the world Posted February 16, 2021 Share Posted February 16, 2021 Are you meaning the lower bush where it mounts to the axle...?If so you need to look to fit a Spherical joint , think in the US you call them Heim joints as the lower mount goes the wrong way and puts a bending moment on the damper shaft during axle articulation which inhibits its operation.

patricklaw7 Posted February 16, 2021 Author Share Posted February 16, 2021 Sorry for the confusion. I am referring to the bush to mount on the shock tower. The shaft that goes through the roll-bar foot plate. It is 7/8" in diameter and the only polyurethane bush that I can find is 12mm. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted February 16, 2021 Area Representative Share Posted February 16, 2021 For us in the UK, we would contact Redline. I'm sure they would send you the right part but I would hope you can fid a west coast supply. http://www.redlinecomponents.co.uk/ Link to comment Share on other sites More sharing options...

Nigel B Posted February 17, 2021 Share Posted February 17, 2021 I have a hazy recollection of a previous Blatchat discussion on the subject of replacing the standard bushes with polyurethane ones. It was of interest to me at the time because I was becoming a bit tired of having to regularly replace the A frame bushes! As I recall the discussion was ultimately inconclusive. Some members had changed to polyurethane & had no problems, but there was also a popular view that having a softer bush in that position was an important aspect of the rear suspension design & replacing it with a harder bush could potentially cause the A frame itself to break. The bush is effectively a sacrificial part, the suspension equivalent of a fuse.Having pondered the various views expressed, I decided not to risk a potential breakage & stick with the standard bush, as the bushes are very cheap & quick & easy to replace. It's a view that's worth bearing in mind anyway, whatever course of action you decide to take. Link to comment Share on other sites More sharing options...
Nigel B Posted February 17, 2021 Share Posted February 17, 2021 Sorry Patrick, I've just realised your post is referring to a different bush! Read the post properly Nigel! Link to comment Share on other sites More sharing options...
