After a somewhat long absence I am now finally removing my rear suspension to get at the brake calipers and change out the rotors (stuck piston ate one rotor) also as long as I am under there gonna replace the whole exhaust (SNG had SS system on sale a while back!.. I also decided to replace all the bushings, shocks etc…I really do not want to take the rear end out ever again (did it on my E type…vowed never again!)
Here is my problem…at least the most serious one (had to cut out the exhaust as the PO welded the whole thing together…I do love my Sawzall!). got the safety bracket and bolt holding the front of the Radius arm and now I cannot get the arm off…any ideas as to how to gt the bushing to release without destroying the arm???
My last problem…what size is the rear radius arm bolt? removed the front shock to get to the bolt but the bolt is frozen…no room for my impact wrench (another wonderful tool!) the bolt seem to be a 3/4 or 19 mm but my wrenchs seem a bit loose…before I round off the bolt head I want to confirm the size…anyone know what size AND hoe to get it loose???
I have already bot the mountings a wee bit loose…had to do something productive today! Brake hose off, park brake disconnected, so I am ready to go IF I can get the Radius arms off!
I WAS hoping to get all this done this weekend, hoilday and all but hting are not looking good!
I am open to any ideas please help!
thanks

Steve, I can’t help you with the rear bolt issue ,but a lister
suggested that I get a crow bar with a sharp edge .Put the edge
agaist the front radius arm lip and give a good push.I had a bad
time prior to his advice tearing the radius arm away from the
cup.Both radius arms came off first try,or rather one cup minus the
arm and one complete radius with cup. I used the pin for the jack
as a leverage point.Worked great and I hope it will be a long time
before I have to drop the rear IRS again. Good luck.
Best Regards

IIRC, the bolt for the rear radius arm has a flat ground on
one side in order to allow it to clear some sort of
protrusion on the axle frame. I don’t recall what wrenches I
used, but can check on it tomorrow, if that will help.
The front radius arm ought to come off with a little
persuasion. Recommended installation is to apply grease
prior to assembly … this could have been left out … or
washed away.
… Hope that you have IRS cage properly supported before
you free up the radius arms. Use a floorjack under the
gearbox tie plate until you get it on the ground.
…Hope you are not trying to disassemble all these bolts
and nuts without some serious rust solvent spray … get
something that will soak in. I use a product called Heat
Valve Lubricant … available only from GM dealers.

The rear radius arm bolt on my 87 XJ6 seems to require a 5/8
wrench. However, if you haven’t flattened out the locking
tab that is probably there, you need to take a closer look
at it.
I think that I used an open end 5/8 wrench on the bolt, and
then used a suitable box end wrench at the free end of the
5/8 as a sort of cheater.
