Well I have a 91 motorhome with a Spartan chassis, called steer-safe and and order their steering stabilizer. I sure hope it improves my drive. Will let you all know. Wish me luck. lol PS I just had a alignment done.
On mine the parking brake is on the drive shaft it would not engaged.It turns out that the lever was rusted at the pivot point. I took it apart and clean and grease it up. Works great now.
