DavidTR4A Posted May 24, 2020 Report Share Posted May 24, 2020 Hi Folks, I was doing a bit of tidying-up underneath today - somehow a postponed activity from autumn 19.... Anyway, all was in pretty good shape but then i did some brushing on a suspicious area near the left trailing arm. The picture shows what happened next. So that's perforations to the right of the trailing arm nut, where the floor pan turns down at the inner sill(?). To the left of the trailing arm nut it's fresh air about 1cm wide ad 3cm long. Frustratingly the trailing arm bolt heads both point at the diff and so i cannot drop the arm easily for better access. It feels to me like some form of L-bracket might be required, after appropriate preparation. I guess this is a pretty common issue so very grateful for any words of advice and general sharing of optimism or fear! Many thanks David Quote Link to post Share on other sites
RogerH Posted May 24, 2020 Report Share Posted May 24, 2020 Hi David, I have just done the same repair on my 4A. As it is, it is an MOT failure if the bottom of the 'B' post has a seat belt attachment. I ended up replacing a section of the lower edge of the wheel arch 2" x 5". A section of floor 5" x 4". A section of the outer sill and the sill closing plate. In your case I would be tempted to remove the trailing arm to give room to understand and sort it.

NigelH Posted May 24, 2020 Report Share Posted May 24, 2020 Hi Roger Given the age of the car, it doesn't need an MOT..appreciate your comment though. Nigel H Quote Link to post Share on other sites
RogerH Posted May 24, 2020 Report Share Posted May 24, 2020 MOT or not when you are in that head on crash you do not want your 'B' post whistling past your ear just before you hit the screen. Roger Quote Link to post Share on other sites
NigelH Posted May 24, 2020 Report Share Posted May 24, 2020 No offence intended..I agreed with your comment.. Nigel H Quote Link to post Share on other sites
RogerH Posted May 24, 2020 Report Share Posted May 24, 2020 Hi Nigel, my post is what my MOT man suggested to me. How often do we need the seat belts. But you know it makes sense. Roger Quote Link to post Share on other sites

Roger Many thanks Roger, yes the B post has a seat belt attachment. I'll give the trailing arm a go and get that better look - at the moment with just poking around all the rest looks pretty solid so fingers crossed. cheers Quote Link to post Share on other sites
tim hunt Posted May 25, 2020 Report Share Posted May 25, 2020 When you drop the trailing arm David take the opportunity for a really close look at the mounting brackets for any incipient cracking, which can occur from the holes where they fit to the chassis outrigger.
