Subject: Lets check out UUC's Delrin bushings in my '96 328is
At UUC Fest, NY, Ben gave me a set of his shifter arm
(front two piece) oval Delrin bushings for my car. He asked me to check them
out and let him know what I thought of them.
Here we go:
On the bench the stock (front one piece) rubber bushing appears to be
When I checked my garage queen, I was surprised at the amount of shifter arm
play when you grab it from below and rotate it on its axis. Although a '96,
this car has only 5,100 miles on it.
When you shift, side to side looking from above, the shifter arm side to
side movement with the stock bushing is not that great. I was also concerned
about buzz from Ben's stiffer Delrin bushings (less isolation). Unlike the
stock bushing there is no need to lubricate the bitch of a clip pin (to get it
in) when using the Delrin bushings.
To install the bushings you will have to remove the bitch of a clip.
for one way to do it.
Once free, rotate the clip 180 degrees to the rear and it will pull right
out. When you rotate it up 90 degrees or so, things get in the way and you
cannot pull it right out on my 328.
Install the Delrin bushings on the new clip (or the one from the car if you
successfully removed it) that they come with. Align the bushings. Rotate one
of the bushings 180 degrees. Select the position where the delta between the
two bushings at the middle intersection is at a minimum. Install the bushings
in the shifting arm maintaining this orientation. Check the alignment out, by
installing the clip. Remount the front of the shift arm by installing the
clip 180 degrees out of its normal location (rotation wise) as noted above.
Rotate the clip 180 degrees forward and lock it in place. Push / pull down
hard enough so that the clip locking tab engages the void / ledge in the
transmission housing. If you can push the clip back up with a screwdriver
from the side that you can see, no cigar. You really have to push / pull
down. Pulling down on a screwdriver positioned horizontally over the top of
the clip works for me.
With the new Delrin bushings, the amount of shifter arm play when you grab
it from below and rotate it on its axis is nil. When you shift, side to side
looking from above, the side to side movement is also reduced but no totally
eliminated. Keep in mind that the rear mount is still made of rubber. No
shift lever buzz noticed. All in all a nice mod if that's what you want to
do, and you can deal with the bitch of a clip. My guess, in the long run, it
will keep you from having to replace the front bushing as often.
Based on the dimensional inconsistency of the UUC bushings I've recently
seen, I can no longer recommend the use of their product. You have no idea
what you will receive when you order from them. If they could guarantee
properly dimensioned stuff, I would purchase bushings from them. Based on
the experience, I will be making my own properly sized ones for the stuff I
