The rebound adjuster knob fell off my rear shock sometime ago. I took a look at the parts break down, but mine has a red rubber part where the mounting screw would go into...or so I thought. Anyone know if the knob can be replaced without going to a shock rebuilder?

#12 & 13 are the parts I need.  Thnks in advance

yes you can replace those 2 parts without taking the shock apart.  there should be a little threaded piece sticking out of the shock, with a flat on it. 

there is no red rubber part there on the stock shocks.  so something else is missing.  post a picture. 

When I get home I'll post a pic of that rubber chingas...

Mine broke **** and broke off long ago.Haven,t been looking that hard but haven,t found one yet either.

Fancy red rubber part............

I really hate not being able to edit mah post, mitch!

I take that back.  They are not the same as in the pictures on part sites.  There is no where for the knob to screw into.  Just a flat head.  I bought a couple because my rezzy one was gone too.

take out that rubber piece, no oil will come out.  there should be a threaded hole there.  and the outside screw should have 2 flats for a knob.

heres some pictures of the adjustment knobs on the 500.  last pic is the 2 parts new from suzuki, knob and screw, and the part numbers.   

87 shock has 2 knobs, one on the rezzie and one on the shock.  88-90 shocks have a slot for the adjuster on the shock, and a knob on the rezzie.
