Our recently acquired 2006 Winnebago Sightseer (29R) was a "whale" to handle on the ride home. We had a constant 25 mph cross wind, with gusts up to 35 mph. Crossing the Brazos river was a white knuckle affair as the wind was channeled down the river and blasted you as you entered the bridge from a wooded stretch which sheltered me from the wind (westbound on US 67). When we got home I took the wife and dog on a trip. My wife almost got seasick from the rolling motion.
A more detailed inspection revealed that the rear sway bushings were gone. Not cracked, not chalking - simply gone. A new set of polyurethane bushings, a new set of Monroe Gas Magnums, and the CHF has made a world of difference.
I used the Hellwig 7692 adjustable sway bar links on the front. When I moved the stock links to the inner hole I had less than one inch clearance before it contacted the springs. I guess that some chassis are built a little different depending on weight ratings. Our chassis/coach is 18K GVWR on a Ford F-53. I set the adjustable end links to match the original geometry, and then used the front links for the rear CHF.
Twas a magnificent improvement! Next up are the SumoSprings - but, when I try to narrow down the choices, the sellers always try to steer me to the Maxim package. I don't need the extra weight carrying. I just want to slow spring rate to give just a bit more stiffness in the curves and cure the understeer. I am looking at the SSR-186-54 for the rear, and the SSF-186-40 for the front. If I can't get a fitment for those from the manufacturer, I will just go to Timbrens. We have used them on our HD diesel pickups with good results. The only issue we have with them is the ride stiffens over time as the original springs settle with use.
As a note, our coach has almost 75K miles. I don't know if the Bilsteins I took off were OE, but they still had a bit of life left in them. Since I bought the unit from PPL, and not directly from the seller, I have little history on the coach.
