Default Front end wobble

Has anyone ever had a problem with front end wobble before, I had a complete front end repair and new steering box but still have a problem. I am starting to think it might be the tires. I have Cooper Tire LT215/85R16 which are 10 ply on my rv right now.
Help me please, this thing is all over the road.

We have a 2007 RT Popular and would experience front end shaking when we were going downhill, super scary. Did a little research and found some others experiencing similar problems. Narrowed down to brake rotors overheating during downhill braking. We were having to pull over when going downhill to allow the rotors to cool down. This would happen even on low gear and with the tow/haul turned on. From what most mechanics have told us, that the brakes for the Chevy Express 2500 van were not designed for the additional weight of a camper van. We had the rotors checked and they could not be machined any further. Rotors were replaced and we will be doing some testing to see if the problem is resolved. So not sure if you are having a similar problem or its something else going on?

I think you will find that rotors will not fix the problem, at least not for long unless you change the brake pads also. Most of us have had good success with high end semi metallic pads, as the ceramic pads don't work all that well in heavy duty applications. The Chevy pads are ceramic and that is what the problem appears to be.


To the OP, you can try swapping front and rear tires to see if that changes anything for a start. If you have them, it would be very interesting to see what they wound up with for wheel alignment numbers after doing all the work. I don't know if the older Fords are settable, or not, without bending things like some of the pickups needed to have done.



The other possibility is that the replacement steering box, which almost certainly is a rebuilt one, is as bad as the original, or even worse. Many of them are horrible. A lot of them can be made better with the adjusters for pinion preload and backlash, but many it doesn't help. It is very common to have essentially no feel for center on them.

Thanks for the suggestion on the semi metallic brake pads. Will look into that as well.

Default Front end wobble

Can you explain the "wobble" a little more?
When is this happening, what speeds?

What is the steering box adjustment? I was not aware the Express van had an adjustment.

I have upgraded the brakes and rotors, and replaced most steering and front suspension components. AND I lube the front end every oil change, which I think is very important. At 60,000 miles since these upgrades I do not have a wobble problem, though I do drive very conservatively in the mountains, using engine braking and keeping my speed down while going downhill.

I haven't looked at the repair manual for the actual one in the van, but it looks like the standard GM rear drive hydraulic box so should be the same style as the one in the old Buick, which I got rebuilt and adjusted at a specialty shop in CA. They filled me in on all the special work they do in getting everything just right. The two settings that can be done externally are the steering shaft input to the gear bearings and the sector preload or clearance to the gear. I will look at the manual to see if they give a specific procedure and specs for the settings.


The pinion bearings keep the gear from moving out of place and causing variable looseness to the sector. Excessive gap to the sector give slop before movement when changing turn direction.

Default Front end Wobble

On our 2007 Pleasure Way Ford
E350 there are Firestone Air Power rear shocks. We were told to set them at 35. With that had same problem you describe. When we set them up to 55 it went away. We almost spent several hundred $ on a front sway bar but this forum suggested the increase setting. Hope this helps.

The wobble is at almost any speed, I’m starting to think that the tires are my problem.
Ford put a label stating to run the size tires before the van was converted which added a lot more weight. I talked to a rep for Cooper tire and he asked what my axle weight was

The rv seems to follow the groves in the road, so I am fighting the steering wheel and this is what is causing the wobble. This is scary going down hills and curves.
