Do I need adjustable upper ball joints?
 

How do I know if I need them. I have a 6" lift on my 03 1500 and the uppers are bad. The wheels lean in on the top. I was looking to buy some MOOG replacements and saw they offer a -3 to +3 degrees of caster or camber. Now I am not sure which way I should go. I was assuming I needed just a stock press in replacement. I am not sure if the wheels have always leaned like that or just since the ball joints started to go bad.

Not saying they don't offer this but it is the first i ever heard about it, i think the only way to know would be to install the stock stuff then have a front end alignment to see where your at.

I would make sure that the knock outs have been removed on the upper arm adjustments are maxed. I worked at a four wheel drive shop for six years and was always amazed how many shops did not do proper alignments after the lift install and told customers they should not expect good tire wear ever again. Both are doable if the lift is done correctly.
