Rear Wheelarch / Bumpstop Corrosion


Recommended Posts

Hi All,

I am in the process of stripping down a relatively sound TR250, but I have found one area of unexpected corrosion. It looks like the suspension bump stop box on the LH Rear wheelarch was not sealed well by the factory, water has got inside and see below. Checking the internet it seems this part is not available new. It looks straight forward to fabricate the box, but can anyone tell me if the heavy gauge lower closing panel should be dished upwards to better locate the bumpstop, or did it start off flat and became dished through hammering by the bumpstop over the years on the road? On my TR6 both are dished.

Regards Ian

p.s. If anyone knows if this part is available could you let me know.

Hi Ian,

on my 4A (same panel) the bottoms of the bump stop support are flat.

I'm sure they become dished over time due to the bump action.

When you sort yours ensure it is well painted/protected inside and there is a hole at the bottom to allow water/moisture to drain out.

It is supposed to be dished at the bottom, You could always as TR Bitz if they have that section left

Different bottom Roger as your bump stop is screwed in there, on the 250 its on the trailing arm.

I'd consider just making one as you suggest as even a good used will have some corrosion and need blasting and painting. Plus its likely to be quicker if you have the sheet already.
