how would you completely eliminate bumpsteer on a bug/bus?

How about start a full resto, that should keep it off the road for the future.

Yes, to get a rack & pinion right is not easy but i dont see no problem with bump steering using long arms,





the only bad thing stays that you need to connect the linkagebox to your rack.... and you need some extra joints for that

That is what I was thinking was one of those aftermarket offroad racks. But, how beafy are they as far as turning the wheels on a much heavier bus?
Also, aren't some of those "quick ratio"?
I see them sold through many venders but it seems hard to find technical info on them.

longer tie-rods run more paralell fore and aft and up and down.

I understand that, but having a suspension where the wheel moves in a different arc than the tie rods will ALWAYS have bumpsteer, how severe is the variable.

Speaking of caster, I just recently saw a guy a Bulli Brigade who notched his beam holes a little over a quarter inch to swing the beam forward and eliminated all squirlyness. He says it drives so well he can use one finger to drive. Says it drives like a Cadillac. And he did it while the beam was still on the bus. :shock:

thats sketchy. and when you simply rotate the beam, now your centerpin is at an angle.


one of my buses has 7 degrees of caster in the beam and it tracks straight as an arrow at 70 mph.

Wanted to bump this up and see if this setup arrived for you yet?

Keith, i will be in florida Feb4 i hope the thing is installed by then ( Or by feb28) I would like to see it (maybe go for a ride?) :D

So, from what info you have on this will it sit higher up than a stock steering box? Maybe eliminating the need for a steering box raise on a super low bus?

this may or may not be an issue of a true rack ect , but i was reading about someones project that they have fitted a CE rack into , the bus is RHD , when the clutch pedal was pushed it hit right on top of the frame that holds it all together , will see if i can dig up a link to the problem and how they fixed it

yes it is higher than a raised steering box...it will help for the mildly lowered bus, but one would have to raise it even more for a very low bus.

Doing Business with CE was great, They have great communication, Ship when they say they will, Packing was good. Product looks and feels good. The parts appear to be made well.

Runboy Tue Dec 16, 2008 7:57 pm

Can you try to get a measurement from the bottom of frame rail to the bottom of stock steering box, and then the same on the new "box" for ground clearance comparison of what this kit offers?
Mike

keith_romer Tue Dec 16, 2008 8:30 pm

will do , It will be a week or two. I am waiting on some other parts to arrive unrelated to the steering.

I have a 2" CB beam w/ drop spindles in my 58. The caster problem was driving me nuts as to how squirrely the bus felt. I took it over to a guy in Town with a racecar shop to have a look at it. He cut a pie-wedge out of the shock towers between the tubes, cut loose the swinglever mount, then bent the lower tube forward a bit adding about 4-5 degees of caster to it. He then just welded gussets across the pie cut, and repositioned the swinglever mount and re-welded it to the beam. The difference in handling is incredible! No more wandering, and constant correcting just to stay in a straight line. I'm thrilled with how it drives now.

I think what some of you may be overlooking is the fact that if your beam is lowered in any way (adjusters, pulled torsions, cut & turn), your castor will be wacked.
I'm not sure what the stock castor angle is at "correct" ride height. Anyone know the spec on that?
I'm pretty sure that leaning the beam back is a bandaid for the problem created by the lower job.
