Diff mounting repair with body in place.

[mleadbeater]

hi, 

as I may have to repair the front diffmountings on my ‘6, I was wondering how others have done this on their cars.

I have only limited access underneath by putting the car on axle stands, and don’t like the thought of welding undef the car.

I was thinking of cutting an access hole in the rear deck behind the seats, as it needs repair anyway, then removing the damaged pin(s) and lower fixing, and fabricating suitable support plates and pins to strengthen the cross member, welded or bolted in position. 

Your experiences and suggestions would be gratefully received, thanks,

I had the same problem and the welding was beyond me, but the way you have described it was exactly how the specialist who repaired it for me did it. He made what I think is a recognised upgrade to these mounts and welded a much stronger set of mounts in place and got access through the floor behind the seats.

Hi Mike, 

             I did it this way many years ago to my brothers TR5, chopped out the rear deck, made up a section of U channel to closely fit over the cross member, then measured and drilled the U channel to take the 2 new pins and welded them in place, after that dropped the fabricated section through the holes left by the old pins and welded it to the cross member, some welding had to be done from below, especially to the support brackets for the diff rubber/poly mounts.

Probably  goes without saying but you must remove the tank and seal off all the pipe work (we also removed the pump and filter).

my friend and I had both our cars repaired from underneath on jack stands. we had the jack stands on top of cinder blocks and the stands were sized for a USA pickup. steady as a rock and plenty of room. I made a sheet metal template that held one pin in place and used the back pins for location. the welder we hired welded the pin around at the top, then did a bottom plate and then boxed that in. I believe the trailing arms were removed.

cheers all, looms like attack from above ( mainly) is feasible.
