I need to replace the bump stops on my trailing arms (TR6) and I have no idea how to go about it. The rubber was pretty worn and just feel apart when I tried to un screw it.

Any suggestions?
 
Try PBBlaster and heat with a torch around the outside of the threads. Then clamp the remaining bump stop with waterpump pliers or vice-grips and crank it out.
 
PB Blaster is available in most auto stores, Walmart too I think. It's a spray penetrating-type oil that will help loosen stuck bolts, rusty bolts and the like. Work great with heat. Ventilate the air.
 
I love PB Blaster.

I have no less than three cans at any given time. I've tried them all, Kano Labs Kroil, LiquidWrench, CRC, Rust Reaper. Pretty much the same thing, but PB is much easier to find.

The stuff really stinks.
 
And besides, PB Blaster will melt a styrofoam cup!

You never know when you might have to melt a styrofoam cup.
 
be careful heating them up, the trailing arms are AL and unlike other metals it doesnt glow when hot it just goes to liquid
 
Well I got one off just fine, the other one broke....now I have a stuck bolt in arm.

I guess I will let it sit with some of the pbblaster in it and try to extract it tomorrow.
 
Tomorrow, heat around the outside of the threads with a propane or MAPP torch. This will expand the threaded hole and the bolt will come out easier. Work the bolt out then turn it back in a little, then back out a little more as you work. Keep the area hot with the torch. Aluminum doesn't melt until around 1400F so with a propane torch it would be hard to melt it, but don't overheat it, just get it hot enough to get the bolt out.
 
There's actually another method you might try. Heat the area (as above) and then rub the broken bolt with a wax candle until it melts down into the threads. The wax gets into the threads and forces the bolt out. I've never tried this but hear that it works.
