Scout II with slight wobble

Submitted by: Daniel K Minor (Milpitas, CA)

After a new set of tires I seemed to have a slight wobble on my '75 SII. Mostly stock, but with 2.5" lift springs and 31" KM2 BFG's. Jeff recommended a 2� shim so I wouldn't cause any other problems. Cleared up the issue and drives much more stable now.

A must with shackles

Submitted by: J Rose (Atwater, CA)

My dad's traveller was weaving side to side when he installed some lift shackles so we put these on and he was back to Cadillac status!
