All - One thing no one mentioned and this coach is part of the group, is the steering gear bracket could have serious cracks if it has not had the modification. If you have done the steering bracket modification, then the other posts most likely have it nailed.

First tire wear should show up if this has been going on for a while, check those for abnormal wear patterns. I personally don't think the 500# tongue weight of the trailer would pull that front end up enough to cause this problem, as we are talking about a front end which weighs in at around 12,000 lbs. With your miliage, shocks, or other front suspension parts could also be the culprit.

Where are you? If near Coburg, cummins NW is one place to see, if in SoCal, then Redlands would be my next choice. If someplace else, Freightliner shops have a great track record with lots of MH owners, so you can stop into one of those, I can recommend the one in Tolleson, AZ(SP). Let us know, but if the as mentioned bracket has not been installed, you might have a cracked steering gear box, and it could be the issue.

Rick; Over the last year we have experienced the same or at least similar problem. It stated with a shake at 45mph that could be stopped by slowing or speeding up. This caused me to think it was a lost weight or tire balance problem, had tires flipped on rims and rebalanced. No change, and it was now covering a wider speed range. So next I changed tie rod and drag link ends. No change, by now I was noticing a cupping at the inner and outer tread (which indicates shocks) I hadn't considered the shock because I puchased new Koni FDS a few years ago when there was a special presented to this forums members, And they didn't feel bad. Well our shimmy/shake or wobble was cured by a new set of RoadKing shocks. Fact is any new shock may have cured the problem but I felt if the Koni's let go after just 15-20000 miles, I would spend more on a beefier shock and expect them to last. (They are not cheap)
My suggestion would be to look at your tread wear pattern, if the fronts are cupping its probably your shocks!
Good luck in your quest!

Wally & Debbie, I believe the Koni's have a lifetime replacement program. You send in the old shocks, they check them, and if bad, reimburse you for the replacements. Road King's is similiar, the burden is on YOU the owner to follow through with sending them back in and them being tested. I won't guarentee this to be fact, it's what I believe I have read on here before as another member had Koni's go bad and got the reimbursement.

Redlands put Konis on two years ago along with steering box reinforcement and motion control. Plus alignment and weighing. Will talk to them.
