straight axle tire shake
 

I have got a new altered chassis and took it to the track today. Just driving around the pits to get a fill for it and the wheels would go into a bad woble or shake at mabey only 5m.p.h. It is a torsion bar straight axle. at first I thought it was bump stear so I took off the shocks and put solid tube inplace of shocks to make solid front. Still didn't help. tried to lean axle back and stand it up nether helped and played with the toe and nohing helped. any ideas would be appreciated

Don't know how much you leaned the axle back or what wheelbase you have, but most people i know are running 10 to 12 degrees Caster, i'm building a 92" Anglia with struts and i'm starting out with 10 degrees.

Make sure everything is tight. All steering components and suspension components. And start with 10 deg. caster. JMO

the car is 125" W.B. to start the axle was 8* caster and had moved it back to 12* and up to 5*. monday I talked to a street rod guy he said they run 5-6* caster and 1/16-1/8" toe in for biasply and 0-1/8" toe out radial. so I set 5.5* caster and almost 0 toe out for my radials and took it for a test drive on the old back top seamed to handle good and no shake. do you think I should try running more caster? on my old 161" F.E.D. I ran 22* caster and 1/8 toe in with good luck.

where would you get a new box and what is ball park price?

A whole lot of Shaking going On
 

Yes i found that there not thick enough and if toe in and toe out is set wrong you will bend that fucker i had to weld a channel to reinforce mine from doing that or get a much bigger dia. bar steering box can be repaired and set up if worn out no big deal to fix them in your own back yard
