I need to replaced caster/ cambers
Any tips or tricks?

 

What do you mean? You adjust caster & camber with an alignment.

 

I have a lift on the truck
So the tires aren't straight
The caster/camber need to be replaced

 

You need to take the truck to an alignment shop.

 

Since you're also in San Antonio give Southwest Brake & Alignment a call. I've known quite a few people that had good experiences with them.

They aren't things that can be replaced, they are measurements. There are three measurements of alignment. Toe: is which direction the wheels are pointed respective to the way the vehicle is facing. Camber: which is the tilt of the wheels / \ or \ /. And caster which is the location of the wheel in the wheel well, forward and backward. This can be measured by center of front wheel to center of back wheel. The wheelbase should be identical on each side.

Your best bet would be an alignment shop bud.

 

Are you talking about replacing the caster / camber bushing that the upper ball joint goes into? If that's what you are looking for Superlift sells them.

Looking back over it that's a poor description of caster. Caster, while it essentially IS the forward and backward location of the wheel, it's more importantly the pivot ANGLE of the wheel. Which is difficult to measure by hand. You can draw an imaginary line through your upper and lower ball joints and it should touch the ground several inches ahead of where the tire touches the ground.

Sorry if this is complicating things, Camber and toe are easy to explain and understand, caster is a harder concept to grasp.

 

Caster - Think of the wheel on a shopping cart - the caster wheels follow the cart. By setting the center of your wheel behind the center point of the i beam the wheel wants to flip back to a " follow the truck" position. It's what makes your steering go back to straight when you let go of the wheel.
Camber is the tip in or out of the wheel or whether or not your tread sits flat on the ground.
Toe-in think of a set of skis straight they go straight, point the tips in the straight gets more controllable, too far in you start to "snowplow". Point the tips out and both skis want to take off in different directions (wander all over the place).
