Okay guys.....I'm letting the motor bit set, so I'm on to suspesnion (something I can actually work on right now) and I need a new set of trailing arm bushings.
I was looking into the Weltmeister Polygraphite bushings because they were a decent price. Anyone have other opinions on these bushings or other ones for below $80? I would love poly-bronze bushings but $260 from pelicanis just a little steep (IMG:style_emoticons/default/laugh.gif) |

More than 50% of the trailing arm pivot shafts we remove look like this:
 After sanding on the belt grinder it is down to the original diameter again:  but, after wire brushing, the deep pits that remain are evident. Installing this shaft into any plastic bushing can't be good for longevity:  I was having the best shafts that I could find centerless ground for a while to true them up without removing too much material. What I found was that the shafts aren't straight enough to true them with removal of only 2 thou diameter, and if there are any pits the .002 removed doesn't get rid of them. So I designed new shafts that are more precise and stronger than the originals:  |
