Attention suspension experts!, left rear trailing arm noise Options

[Elliot Cannon]

During my trip to the WCR I had a VERY loud squeek from the left rear suspension. After removing the shock, break and rear sway bar I can lift the trailing arm up with NO resistance and NO noise. Is it possible that it could be noisy only with the weight of the car on it? I bought some polygraphite bushings for it. Should I use them or opt for the more expensive roller bearing bushing, or poly bronze etc.? Are the rear roller bearing bushings even available any more?
Cheers, Elliot

Polygraphite bushings are well known for squeeking. They probably need to be greased. Neuspeed (H20 VW nuts) recommends their own grease for their bushings, it's just silicone grease.
I can't see any zerk fittings in your photo. You can either disassemble the suspension and grease things or add zerks and put about 25 tubes of grease in there the first time to fill up all the space and then a few squeezes of grease here and there as it needs it. I like to groove the polygraphite bushings and drill them so that the grease will make it everywhere.
There's no guarantee that the bushings are your problem but it seems likely to me. I've seen them not make any noise without the car's weight on the and then start squeeking again as soon as you put it on the ground.
The Elephant Racing bronze bushings don't squeek and neither do the roller bearings, but they both cost some real money compared to the polygraphite.
Personally I'd grease the existing bushings until I got sick of it and then I'd go spend some money.
I have the plastic bushings. I figure that the $1000.00 spent on bushings won't make me faster around the track. $1000.00 spent on more track time will.
