How important is the rubber dust boot on the steering damper where it ties into the lower fork tree?

This rubber dust boot/spacer sits between the ball in the fork tree and the steering damper.

While I was replacing my OEM shocks with new shocks this past weekend, I noticed that this rubber part was breaking down and falling apart. Other than being a prevention for dirt getting into the ball socket, I don't see any other purpose. Steering damper is still working fine...I don't want to remove the damper from the bike if I don't have to.

Also when looking at MAX BMW parts fiche....I don't see this part listed. Is it the same part that goes on either side of the other end of the steering damper as it ties into the leading link? There are two rubber rings on that end of the steering damper.

Thanks for the help.

Best to keep dust, grime and dirt out of swivel joints. The part you need can be cut or punched from insulation material such as closed cell neoprene foam rubber.

I had the same problem and found an excellent replacement http://www.ebay.com/itm/BMW-Ball-Jo...rcycles_Parts_Accessories&hash=item20cedcadb2 . Cost was not bad and the rubber on the replacement boot is definitely much better than the original. After replacing the boot I bought an extra just in case.

I also found a fairly helpful 3 part video on You Tube that walked through a replacement: Part 1 https://www.youtube.com/watch?v=gY_bqxzT0XY Part 2 https://www.youtube.com/watch?v=XZ-cKHjlF0A Part 3 https://www.youtube.com/watch?v=-NasPhtj64U . A bit of a pain as I had to remove the front wheel, steering stabilizer (good time to refill it) but well worth it in the end. One tip, there are two very tight rings to hold the boot in place (top and bottom). Once removed they are nearly impossible to replace (my opinion). I used some very fine zip ties to secure them with perfect success.

Luck!

Thanks for the replies.

Silverlt2002.

That boot shown in the link you provided would be used on the Leading link ball joint that ties into the lower fork tree. Which is the center mounted ball joint on the lower fork tree.

I am asking about the rubber ring that is on the smaller ball joint ( to the right of the Leading link ball joint) that the steering damper uses to tie into the lower fork tree.

the parts fiche just shows a round rubber ring without any ribs.

I agree that keeping dirt, grime and stuff out of the ball joint is important.

Does anyone know of a source for the rubber ring around the smaller ball joint. I do like the idea of closed cell foam...I probably have some in the garage.

Thanks

I like the garden hose washer. I thought rubber grommets might also work.

Probably makes some of the BMW parts only gurus cringe.

Reminds me of the book, "Zen and the Art of Motorcycle Maintenance" and the section about using aluminum beer cans for shims to fix loose handle bars.

An excellent read.

Thanks for the suggestion.
