Super Steer bell cranks for Freightliner XC chassis

If your rig has bell cranks on both sides as my P-30, then yes, you need to replace both sides.

I don't think that Henderson's makes a Bellcrank for Freightliner chassis. They are for P-30 and P-32 motorhomes.

Should be able to adjust slack in steering box, granted bell crank could be worn. Adjustments are made on outside of steering box.

I'm looking at their catalog right now.
The part number for the Freightliner XC chassis is SS100.

Are you sure it is the bell crank and not the tires?

Does anyone have any experience with these units?
After the marked improvement from the Koni FSD shocks, I looking now to eliminate the constant back and forth movement of the steering wheel needed to keep the rig on a straight track.
And, do I need to have them put on both sides of the rig?

Might want to check the play in the steering box. I have no wander with ours what so ever. It is a pleasure to drive and don't need to keep working the wheel.

Henderson's does have them for the XC because I put one on my previous coach. I would make sure all the other steering components are OK before spending the money for the bell crank. In my case, my OEM bell crank was sticking and the Supersteer unit is bearing smooth. It improved tracking in my coach with the XC chassis.

First of all, I have not changed the bell crank, so I can not comment on that.

Your rig (from your profile = 1999 Newmar Dutch Star 38' diesel pusher) will be on basically the same chassis as my motorhome. I've chased the same problems, and have solved them without replacing the bellcrank. Mine seemed to have excessive steering play.

Yes, the Koni FSD helped the ride a lot. After a good alignment, I still had the problem you described. After checking for worn components, I determined the loose feeling was from the steering gear box. Luckily, it is adjustable. After minor adjustment, it tracks much better.

I could still feel the tires following the ruts in the road (very minor problem) and installing a Steer Safe cured that problem.

Adjusting the steering gear box is a controversial subject. Some authorities claim you must remove the box and make adjustments off the rig to get it right. Many shops refuse to adjust the steering gear box. There are a number of Freightliner chassis owners that have realized improvements by adjusting the excess slop out of the gear box without removing the gear box. The adjustment is on the side of the gearbox, with a hole in the frame member provided to allow access to it. Make very minor changes and test drive. It's better to be a little loose than too tight.

There is additional info about this on the Freightliner Chassis Owners Group on IRV2.

The Michelin tires are two years old with about 6K miles and no signs of uneven wear.
