B-body spindles and bumpsteer (again)

[1BadElky]

this is a quote from a recent thread that got me thinking...

Lower the inner tierod.

Warning if you do chicken **** welding don't try this at home.

when installed on a G-body or S-series, lowering the centerlink will improve the bumpsteer issue, correct?

what if you used a pitman arm and idler arm that would lower the center link? I think 4wd s10s have a steeper angle on the arms that could accomplish this, but if this is not the case, could the pitman/idler from another car work? possibly a Camaro or the B-body? Maybe even some jeeps?

just wanted to throw that out there... I could be way off.

anyone?

I would say that you would need to determine what the "bump steer issue" is. Do you have toe in on bump, toe out on droop, or the opposite, or something else. Only after knowing that can you begin to determine what will solve the problem. Vehicle static ride height is a consideration also.

Need more info...

Understand there are two issues- one is bump steer, one is steering speed (the B body spindles apparently slow down the A/G body steering.)

Not certain- is the end of the steering arm is too low or too high for the application, but it seems that raising or lowering the center link as appropriateregardless of the method, should resolve the bump steer. The seering speed would probably need tobe addressed w/different pitman and idler arms.

Another option is using somethinlg like Coleman spindles w/ removeable steering arms.

There was a guy, think he was on here or corner carvers, who had an elCamino- and a website On-rails rcing or something like that who pursued that option. Although I've looked for it recently, it seems to have disappeared.

That was Dennis, look him up as "sinned" on Team Chevelle.

I'm not familiar with G-bodies, but on an A-body, the B-body steer arm is too low. Lowering the inner tie-rods at the center link would help.

The B steering arm is too long which slows it as well as changing the ackerman. It is also too low for the G body, more so than the A body. Stock car suppliers have adjustable center links and idlers, and/or you may be able to move the tie rod to the top of the arm, but a better solution is the Blazer spindle, the arms are the same as a stock G. You can use Howe ball joints to change the geometry and a 'standard' type bump steer kit can be used to dial it in. It also has bolt on hubs so adapting modern brakes is easier.

Is there a reason to use the Blazer rather than the stock G-body w/ the tall BJ? Not considering possible brake modification,just suspension camber curve and steering....

That maybe true when your talking about early a-bodies. If my measurements were correct the g-body steering arms are a hair longer than the b-body steering arm.
