Guest Andy405 Posted April 5, 2006 I have been told that the 205 uses the same setup as the 405 on the rear, meaning the torsion bar. My question is, how do you lower the rear? is the any info on the net giving a guide on how to this or can anyone on here give me some help? Cheers. Share this post Link to post Share on other sites
Guest Andy405 Posted April 5, 2006 Just found a guide on this site http://www.205gtidrivers.com/articles/b-re...lelowering.html would it be the same for a 405 1 spline and thats it? Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted April 5, 2006 I haven't done a 405 beam but it should be the same in principle looking at the 405 Haynes manual. The lowering guide is wrong imo in step 9, the stud should be adjusted so it is against the cap on the centre tube & the arm has the correct clearance. This is explained in the rear beam refurb guide also on the site. With the bars fully home in their splined hole, fit the offset washer and rotate it until the screw can be inserted. Tighten the screw up and at the same time, wobble the trailing arm up and down to take the weight off the torsion bar. When tight, move to the opposite end where the screw stud is. Wind the stud all the way in until it stops but do not over tighten it. Fit the nut and then tighten it so that it pulls the stud and bar. If the stud rotates, use a screwdriver to hold it in place. It will get quite tight and you should be able to see the bar move very slightly. Now release the nut until it becomes loose. Check the relative trailing arm for any gap between it and the cross tube. There shouldn’t really be any gap, as the seal will butt up against the arm. Go back to the stud and wind it out slowly until you feel it butt up against the outer cup. Stop at this point and hold it in place with the screwdriver. Now tighten up the nut so it tightens the stud preventing it from turning. Do the same for the other torsion bar. Refurbishing the beam is even more important on the 405 though as they suffer even worse than the 205 imo. Trying to lower the beam one spline can kill the beam in a very short time even if it seems OK now but that isn't the best way to lower the beam. It can be lowered any amout to the mm using the correct method with both ends of the torsion bar removed. Graham. Share this post Link to post Share on other sites
