I did my spring pans with powerflex at the weekend.. Easy.. My little sister could have done it. Undo and knock out the big bolt that goes through the upright .. spring just falls out, no need for a spring compresser. Undo and knock out the bolt that goes through the subframe. pull the the springpan arm out of the subframe. Put an ordinary blowlamp on the old bushes, the old rubber bush will just fall out after about five mins. That leaves the metal sleeve in the arm, it's very thin, only about one millimeter thick, put the springpan arm in a vice, thread the blade of an hacksaw through the hole. Saw most of the way through the sleeve, try not to cut into the spring arm. A few scratches won't matter. Get a small sharp chisel and whack the sleeve out of the arm, clean up the inside of the hole with a bit of emery paper.
Do the same other end.
Smear copper ease into the hole. Whack the plastic bushes in from either side, until they are fully home. On the inner bush.. knock the metal inner bush into the plastic bush.. NOW THIS IS THE IMPORTANT BIT!. you will see that the metal inner bush is about two millimeters shorter than the plastic bushes. So make sure that when the inner bush is in place you have one millimeter of plastic bush standing proud either side..GEDDIT! Now some garages then use a hydraulic jack to force the bush into the subframe..I don't like this because it will put a massive longtitudinal load onto the subframe bracket, and there's one Aussie guy on here who snapped a subframe bracket off doing it this way, the fact of the matter is the plastic bushes are two millimeters to big for the subframe, but the metal inner bush is bang on. So get some abrasive paper put it onto a flat surface and lap down the plastic bushes until you just start to scratch the inner metal bush, keep it even as you can. constantly testing for fit in the subframe as you do it. It should be a tight hand push fit into the subframe. Smear copper ease onto the ends of the inner bush and hand push it into place locating the bolt as you go. Put the nut on loose and make sure that the arm it free to pivot. Do the same on the outer end.
When assembled torque everything up...
Tools needed.....socket set..spanners..torque wrench..blowlamp..small cold chisel..hacksaw.. hammer.. emery..flat surface.. vice or workmate or something.
When it's done it's brilliant.. feels like a new car.
Think that's about it..Little sister's doing the next one.
