I know I’m getting ahead of myself, but in about 6 months I’ll have a shop with a lift and I want to change out the bushings and upgrade to a set of Peter Cs rebuilt shocks. It’s a 2 post lift and I’m assuming that something along the lines of a transmission jack would be helpful to hold up the rear end. Any thoughts from those who have done this will be greatly appreciated!
Thanks, Rut

You do not have rebound rubbers fitted?
would do one side at a time. The rubbers will keep the axle from falling out.

A tranny jack is almost necessity for that job. I've seem many MG's through our shop with loose and/or worn rear dampers. They can be the cause of various mysterious clunks and rattles. Use new shackle bolts and be sure to replace the vertical links, too.


EDIT: Although I've "trusted" the rebound straps occasionally, I've also seen them deteriorated to a point of failure. Those would be another part I'd replace if doing the job.

Thanks guys, I do have rebound straps, but don’t know the condition and while the rear is fairly solid I can tell that it needs attention. It’s about the only thing on the car that I haven’t worked on. The poly bushing have been sitting in the boot for well over a year, but when the shop burned I kinda lost my passion for awhile. I hate working in the garage and taking up my wife’s parking spot and not having the tools I need to do the job right.
Thanks, Rut

While I’m thinking about this, does anyone have a suggestion for a transmission jack? I’ve never even used one and don’t know the differences that would be good for a home hobbiest.
Thanks, Rut

How far up in the air will the lift go?That would determine what you will want for a tranny jack. If you can work low, a normal floor jack can work. Just looked at Northern Tool website, they have a variety of them.

We had Nussbaum two-posters in the shop, the trans jack was a steel four foot high tripod with a 24" screw post centered. Crude but dependable.

I took my TF rear out by putting the car on jack stands, dropped the springs in the rear and lowered the housing with a floor jack. I had the gears changed from 4.8 to 4.1 and the rear totally rebuilt with new axles, bearings and seals. It was easier than I initially thought it would be. The 1200 bucks to have it rebuilt hurt a little but the rest was easy. :encouragement: PJ

The lift is a 2 post asymmetrical with a stop bar at about 12’, so there’s well over 6’ of room to work underneath even on my crew cab GMC. I think a screw type would work well if I can find one with an axle cradle adapter...I need to see what’s out there.
Thanks, Rut
