Squeaking torsion bar bushing

[biotex]

I see this is a common ailment, and am wondering if anyone has simply installed a zirk fitting onto the cover so they could pump some grease into it.

My guess is that the rubber bushing is ovaled and contacting the top of the cover. I would be willing to replace the bushing if I can remove the cover without fear of the tension being released. This would only apply to the outer bushing I realize.

Anybody have any input to the zirk fix?

In most cases you can replace the bushing without worrying about unloading the spring plate. When you put the car in the air, the spring plate, shock, and rear axle tube (or shaft if it's IRS) are still bolted together and keep the plate from slipping off the lower lip of the stop. Here's what I mean.



You'll note the dust cover and the bushing are both off here and the suspension's at maximum droop because the spring plate's sitting on the stop. To get it off, we had to unbolt the shock and spring plate from the axle tube and then use a prybar to work it out and over the bottom lip. It wasn't going anywhere with just our hands. If you want to play it safe, chain it up so it can't move, but to just swap the outer bushings is a fast and easy job (barring rust)

Do you know if the bushing's been replaced before? Urethane bushings squeak even if you lube them so that may be your problem.

I'm not sure a zerk will work, it's not really a sealed cover on there, so greasing it will just cause it to goop out after a certain point and make a mess.

Thanks for such a detailed explanation. Makes sense. I'll remove the cover and see what is behind it.
