71 Super IRS with very squeaky rear rhs suspension

Hi,

Need expert advice,
71 Super with IRS and it has a very bad squeak. It's driving me crazy.
I think I saw some time ago to use talc powder on the rubbers or grease?
What is the best remedy, it's only on the drivers side, at the moment.
Thanks
Darryl

Rubber grease is best but you will have to pull apart to insert grease

most probably the rubber is worn needs replacing

you can prob get away with removing the end cover n fitting new rubbers with grease

Have you stood on the rear bumper n bounced it around to check noise

Oh an do both sides same time

Try a silicone spray on the bushes, it has always worked for me, jack the car up on stands and unload the bushes, it can do no harm and will work without dismantling the suspension.

I replaced the both side rubbers with poly ones and didn't grease them over 2 years ago, car has only 18,000 klms after full rebuild, only drivers side squeaks ,
I'll pull it apart and apply rubber grease.

Thanks for the information,
Darryl

When checking the squeak at first thought it was from the front, but on checking found it to be the rear drivers side, passenger side is ok at the moment.
Thanks for the input

I tried that and it didn't work, what I did find was that the end cover over the suspension torsion bar is not in the centre of the cover plate and I cannot put a feeler gauge between it and the cover plate. so something is amiss,
I wont know until I full it apart.
Thanks for the help.
