Ever get that grocery cart that has that one wheel that wobbles faster you go more it wobbles that because its caster off. Same principle apply to front wheels on axles.

How so? Stick angle finder on diff look at chart.

no still not quite getting why the hell he spent all that time making the chart. or why he even involved the diff he's just making it more complicated. set an angle finder on the C and find your caster. make sure it's between 5 and 7 degrees negative caster

I don't have a D30 anymore so I have no way of checking this. can you get 5* positive caster on a lifted D30?

I give up. use that chart if you can figure it out. I'm too s-s-s-stoopid

OP printout is 9 degrees. The link in your sig says 5 to 7 degrees. Not negative.

Well I'm thoroughly confused now. Does any of this hold true for my 2-wheel drive since it is a straight axle without a drive shaft? Isn't that where the vibs derive from to begin with?

sorry. no you're good. just get new arms when you can to push your axle forward
