Can someone please clue me into where i can find the alignment specs for this truck. Also, are there any tricks to aligning this beast or any special machine required to achieve proper alignment. Thanks/Clay

Crap - i just read my first post and i made it sound like i was doin this myself. Let me say I have had my sled at a front end shop 4 or 5 times and they can't seem to get the front end alignment right. They have replaced upper and lower ball-joints with moog adjustable uppers and moog lowers and they say there isnt anything else that needs to be replaced to stop the truck from wandering but i am "wondering" if there is a better alignment setting than what the manual calls for?

Does it pull to the right as they all seem to even in perfect alignment? You also have to consider road crown.

It doenst come back to center very well. Its like when you correct it it overcorrects every time and you wind up going right left right left right left.

I have tried 2 or 3 different PSI combos and can't seem to get that to help either. 50 PSI's in each tire is what i currently have. I am still thinkin it could be related to the moog adjustable upper ball joints but want more info before i take them off.

I just called Federal - Mogul Corporation (owns Moog) and spoke with a tech that said they are now making non-adjustable upper ball joints for a dodge diesel but that they are on back-order. He was very aware that Moog adjustable upper ball joints were causing alignment issues.

Here are the specs he gave me for a Dodge 2500 4x4 deisel QC Short Bed:

Castor = 4 Degrees (Min = 3.25, Max = 4.7)
Camber = 0 degrees (Min = -.5, Max = +1)
Toe = +.10 (Min = 0, Max = .20)

He said that a truck could still be properly aligned with the adjustable uppers but may take a few trial and error runs of slowly adding castor until you are happy with its drivability.

Anybody have any experience with this? Please speak your results.

Mine is still the same - all over the road and dangerous. Im thinkin its time to remove the adjustable uppers and install Carli uppers or spicer uppers. No problem money couldnt solve.
