I have an alignment question that i'm hoping someone here can answer. So my signature truck chewed through my last set of 285 tires so I went through the entire front end and replaced what needed to be replaced, got new tires (265's) and took it to the shop for an alignment and the guy said he can't do a proper alignment unless I install new camber/caster bushings. Does this sound right? My truck isn't lifted and my new 265 tires are the same ride height as the stock tires.

That is absolutely correct. I did a full rebuild on my dad's old Dana 50, new ball joints, bushings, the works. They still had to replace the castle nut looking things on the ball joints to true it up. Drove like an absolute dream after.

They are adjustable, but if you can't get them in spec, you replace the adjusters with ones with either greater or less angle on them.

Oh I see. So if you look at the alignment report that I attached to the OP, what bushings would i need? I see on rockauto that i have several options and i'm not sure which ones to get. Sorry, but alignment talk isn't something that i'm too familiar with.

The machine should have told him what bushings to install. See if it says it on the sheet or see if he stored your alignment on the machine and can call it back up. The machine figures this out, its not easy picking the correct bushings. The caster and camber are both adjusted with this bushing, so both specs have to be aligned at the same time with one bushing.

It is the alignment guys job to see what bushings are needed and install them. They just tend to be lazy about this, as the bushings if they havent been out in awhile can be difficult to get out if you dont know what you are doing.

The problem with just buying bushings and installing them is, that you dont know how much correction is already being provided by the current bushing.

Did you check if the springs are sagging? That would cause negative camber.
I haven't but it looks just like every other obs F-250 with the front sitting lower than the rear. I read that you just measure the gap between the leaf spring and the rubber stop and anything less than 1" would be considered sagging? Is this accurate?

I don't remember the exact number but that sounds about right. Roughly 3" between the beam and the frame is another number that comes to mind. The alignment show should also know the correct specification but it's worth asking just in case.

I am surprised they are going to the trouble to do the bushing at all. They usually just set the toe and charge you $60.

And these guys should guarentee their work. Make sure you get the sheet he gave you the first go round, the last sheet should be all in green.
