rear end bushings

im in the process of re-building the rear end in my 88 tc and the stock bushings on the top of the axle, the ones that connect to the upper control arms, are worn out. I am looking in to getting some PST polygraphite replacements. I already have some new CHE upper and lower control arms so those bushings are fine. I am looking at PST'S catalog and they show a "rear bushing set" does anybody know what all is included in this kit? I just need the two top bushings, but they have a 77-79 t-bird upper bushing kit, and a 80-88 lower bushing kit. Also, they list them as either round or oval, im pretty sure they are round in an 88 tc(?)

Also i think i need to reuse the stock bushing shells right? Whats the easier way to get the bushings out of the shells? Thanks.

The best way is to torch them out. It took me many hours to get the old bushings out of the arms. Then I got smart and had a friend heat them up to where thewy started burning with an oxy torch and they slid right out like budder on a hot plate. They are round on the axle. The oval bushings are the front lowers.

It is best to rubber in the axle bushings on anything that doesn't only go in a straight line. But that's up to you. MM sells the bushings and a tool to remove and install the bushings.

The oval upper bushings are for the chassis mount in the uppers. As mentioned by darkthunder, almost all recommend rubber bushings in the upper axle mounts. If you look at the uppers, as they move up/down they bind due to the geometry. Rubber will give you smoother motion, even though that's a compromise. Ford has a replacement, Ford Performance Parts M-4050-B 8.8" Axle Installation Kit, Rear UCA axle housing bushings only, rubber, that includes the metal shells. Try Summit for them, around $15. It will make it easier if you get a puller/installer as mentioned.

i think ill go with the summit kit:

it includes the friction modifier which i need anyways. i will bring the axle to work and heat them up with a torch to get the old bushings out. It looks like the summit kit bushings include new shells though, how would i get the old shells out, heat them up? Also, what are those c-clips for?

The C clips are replacements for the axles, inside the differential housing, if you were to remove the axles. The old shells will need to be pressed out and the new pressed in. It helps to have the right tool to do this. If you work at an auto shop they might have one. Or MMC sells a tool for this purpose.

One more question, what would be the best weight of gear lube to use in my axle? I have 3.73 gears and a auburn posi unit in it, i was thinking 75w140. Don't really want to pay $10 or so a quart for royal purple or anything. Plus with the summit bushing kit i will be getting friction modifier anyways. But i do want to use synthetic gear lube.

Why not the Royal Purple? It's not like engine oil. You won't be changing it for a long time. With the Royal Purple you don't need friction modifier.
