Panhard and Track Bar or Trac bar are the same.

They exist to locate the axle from side to side. Without them on your F53 the axles is only located by the springs, and that just isn't enough.

The other bar being mentioned here is the Antisway bar or anti roll bar. It does something very different and important job.. It is a spring, and unlike the suspension springs that work all the time, it only works when one wheel tires to move differently than the other wheel. So if you hit a bump and both front wheels try to pivot up 1", the antisway bar does nothing. Now go into right hand corner. The left side front tire will try to move up towards the chassis and the right side front tire will try to move down. Of course, we feel the coach body moving but that is because the springs allow it. The anti sway bars resit this.

Both of these together help with the push you feel by passing trucks. I really don't think the steering stabilizer does anything for this kind of issue.

I did the same thing. Great tracking. Couldn't be better. I had to sign a paper from the Ford dealer limiting their liability from going above specs...

Really???? You had to sign a paper relieving them of liability??? There's no liability issues with this. How utterly ignorant on their part. What possible negative effect would/could occur if you went above the listed caster settings?

1. It would not increase tire wear so you couldn't come back and demand new tires.

2. You have power steering so you won't come back and tell them you get worn out steering the RV.

3. It's your vehicle and your $$$$$.

4. You are hiring them to do your work.

When I was a kid I worked for my parents for 5 years and we always considered for the best customer relations the "Customer was always right." Even when or if they weren't.

OK now I remember. The lawyers yes the lawyers. A few years ago our SIL was picking up his new vehicle and he asked them to add 2 more lbs of air in the tires. They refused to do it because it would have put them over the listed sticker pressures. LOL!!! Yes I had a good laugh as well!!!

Are you sure you are above specs?

Jeff..Although we have a 2000 Georgie Boy 31' Maverick "C" on a Ford E450 chassis, I can fully agree on the caster effects, at least for us. When we got the unit in Jan 2014, the dealer had us take into a truck shop for an alignment. It turned out OK....A trip to Moab shortly there after brought out the problems. I then started reading the threads and comments here about the caster settings....esp., from Harvard. I checked the data from the first alignment and found that it was set at about 3 1/2 degrees positive...about in the middle of Ford's recommended range. Shortly before a cross country trip to Maryland in fall of 2016, I returned to the shop where the first alignment was done. I talked to the service manager and he knew of the problems with the E450's and was happy to increase the caster as I asked. The alignment tech was also familiar with it and ended up with settings close to 5.5 degrees positive. WHAT A DIFFERENCE! The unit tracked straight down the road, passing semis no longer caused a white knuckle hold on the wheel, and overall it was just a lot more enjoyable. It did however increase steering effort a little but not anything to worry about. But, be sure that the shop you go to is willing to "think outside of the box". Our first alignment was "plain vanilla", right in the middle like it was always done. Second time out, they were very willing to increase settings beyond what normally would be done, and still stay with in Ford's guidelines (0-7 degrees, I believe). I realize that our E450 chassis is an entirely different animal than yours, but I was trying to add support to the caster increase thinking and how it helped us......if you go down that road.

[QUOTE=Harvard;4629837]Are you sure you are above specs?

Yep, I'm sure. I think the max caster plus in the manual is 5 or 5.5. I had them set mine to 6. Amazing difference.

Steering stabilizer such as the safe-t-plus do a great job at mitigating side wind conditions and the push from passing trucks.

It needs quad rear shocks, and the sway bushings replaced with poly (installed and greased correctly, not thrown on a lift and tightened down while the springs are extended) Dual steering stabilizers, and air pressure set to load. Class A gassers suck, I know, I have one on a p30 chassis. Get it weighed, if it has air adjustable shocks you will also find its too low in the front.
