Bump Steer

[Solitude]

It has a little to do with the short wheel base too.. I drove over a steel bridge in oakland once that caused it to kinda porpoise sideways over the bridge

Bart,

Yes, short wheelbase vehicles HATE washboard. Mushier springs will help some but will not solve the problem.

The bump steer I'm talking about is a single bump at speed that some have mentioned is bad enough to cause an inadvertent lane change.

Thmstec,

Thanks for the tip. Judging by the responses, it doesn't look like I need to start a poll on this thread but I'll try to 'member for the next time.

I'll have 'Welder Guy' fab up a prototype to try out on CSTYLES' VX since he has both symptoms. I'll let you know how it goes.

Look at Baja trucks. They're so soft, they are difficult to drive on anything other than straight pavement. Isuzu realized these things would spend %90 of their life on pavement and built accordingly. I'd hate to soften this thing up.

Well, then I can safely say I have never experienced what you are talking about. It sounds scary.

I experience this on a daily basis. But I have to say It scared the snot outa my nose the first time it happened.

There is a crease between the off ramp and the bridge where I exit the freeway everyday and if I get the green light, I’m coming in at least 45mph and hit the bump mid way in the turn; my back end always pops up and shifts to the right throwing off my "line" of driving. But I’m so used to it now that I already know how to compensate for the bump. I’ve got the Rancho 9000xl installed and set to number 9 and sitting in the stock stance btw. Setting it any lower I float around like a semi truck cab sitting on springs or something…
