I know our PSDs are known to have negative camber and eat up the inside of the front tires, but does anyone know how to help out this situation? Just replaced ball joint 10K miles ago and still doing so. Any help?

 

Camber bushings

 

Where do you get them from? How do they work? Are they safe? What do those run for a set?

 

I have 218K and never have experienced negative camber. I think you are thinking of the OBS F250's with the split axle.

 

Yes my truck is a 250. What is the OBS 250s with a split axle?

 

They can adjust the camber with camber bushings. Your truck should already have them installed but it's possible that it doesn't. Some alignment shops will tell you that there is no adjustment for the camber angle and they're full of crap. It can be adjusted, they just have to know how to do it and not be lazy.

 

Where can you find camber bushings? Dealer, auto parts store?

 

Def an alignment shop. On my 95 OBS diesel I have the stock twin eye beam front axel that pivets in the middle. Usually when you experience this it is ***** joints but in your case I would put monney on bushings. My truck had alot of positive camber so it was eating up the outside. Took it to my friends at the alignment shop that my buddies own and they put bushings in. Bam problem solved. And it only cost me 157 to 175 to get them put in at the shop. They said that was standard price. I hop this helps Robinson

 

Have you had a professional alignment done?


There are cams around the upper ball joints that can be swapped to adjust caster and/or camber.

Did you do the ball joints yourself?


Here's an example of a stock cam vs. a cam designed to give more positive caster:



As for what cam if any you need.....you'd have to have it put on an alignment rack to see what your current settings are.

 

Must be done at an alignment shop. There are several different degrees of bushishings from .25 to 1.5. They can be used to adjust camber, caster, or a combination of both. I have done lots of these on Super Duties. Usually .25 to .75 degrees will fix the problem. I charged 1hr. labor per side to install the bushings.The bushings run about $35 each. It is a little spendy but so are tires and the truck will drive MUCH better. Any good alignment shop should be able to help. Watch out for shops that do a "toe and go" special. The spec on the SD should be +.25 to -.25 camber with no more than .50 difference from side to side. Caster should be around -5.0 +or- 1.0 no more than .5 difference from side to side. I am pulling that from memory and its been a couple years so it may be off some. Always ask for a print out of the before and after readings. Hope this helps.

 

Actually you can get larger bushings than 1.5*......the ones on the right in the picture I posted are 2.25* caster.

 

Just proves after being out of the biz for 6 years I don't have it all memorized anymore.

 

They'll be going on my 07 F-350...hopefully next week.
