Hello all; I am putting a 1928 Buick 28-10 Sedan and I am wondering if any of you have information on what the factory alignment specs were for this or where I might find such info. Or is there a good starting point for a straight axle car that others use? I have modified the spindles to accept 63 Chevy front hubs and am going with a S-10 rear end. Thanks
Pretty common on any straight axle-1/16 to 1/8 of toe in. stick a square up against the I beam and when touching the bottom web you have some clearance to the top web I say the caster is good too. Have fun!
I agree with rusty valley on tie in. You may have trouble finding a shop that still uses fractions of an inch for front end adjustments. Young guys use degrees. I set it myself last time and am happy with the result.
I have a Longacre caster/camber gauge (bubble type) and was looking to get a starting point for what I should look for. I know they make tapered shims or you bend the axle(not my choice here). I would have guessed 5/64" toe in. Thanks for the reply's
Use tapered shims for caster; bend the axle for camber. Sorry, it's the way it's (was) done. Where'd you get that measurement for toe? 5/64"??? Good setting, but reduce it to its lowest terms...(1/16"-1/8")
I have an old Motors manual that has alignment specs, but unfortunately it only goes back to 1935. For what it's worth a Model 40 Buick that year had specs of +3 degrees caster, +7/8 degrees camber, 5/32 inch toe in, and 5 degrees kingpin inclination.
Unless the axle was damaged there is usually no reason to change camber. I'd set the toe in at 1/8" and start out with 4 degrees positive caster. Camber has to be changed by bending the axle in the correct spots on a front end rack setup so that you can tie it down and usually using a 50 ton bottle jack. It's not a home garage project for 99/999 % of the people working on their own cars. The main reason for changing camber on an I beam would be that you have more camber than your wider tires want to deal with and are wearing one side of the tire far more than the other side.
