Change the steering sector if there is no slack in any of the steering links.Had this happen on a street stock.Sector seemed fine but when I changed it problem went away.

I had this happen a few years back in a hobby
stock. It is from caster split.I replaced every thing in the front end before I found
out.It wont hurt anything to leave it like it is.It takes things to get just right(or wrong)for it to happen.Or you can take some split out.

if you are running a remote canister for the p\s pump, while the engine is running, open the cap & look inside to see how much fluid is being pumped. If you are running a steering quickner, disconnect the steering shaft from the sector & turn the wheel. If you feel a bind, inspect the quickner and ant u joints that are in the shaft. A 3 degree split in caster won't make the wheel shake. check to see if the tires are badly out of round. Also check the run out on the front wheels. All of these things can give you a shimmy at low speed. Hope this helps you!!

It is not as much the split as it is an effect of pos. caster. the split and a few other things at the same time make this happen. This is the same thing you see on a sprint car front end and on a shopping buggy
I have done front end work for a living for 15 years and have also seen this on street cars and trucks with as little as 1.5 split
when hitting bumps.But I am sure somebody will say that I am wrong but try adjusting
the front end before you spend $$$ it is free
