4.7 V8 WJ - Upper Ball Joint

I recently took my 2000 WJ to get an alignment check and found an interesting problem.

The jeep's caster alignment is at 5.4 and 5.5 degrees (Left and Right).

Chrystler's specified range is between 6 and 7.5 degrees.

The shop is recomending that I replace the adjustable upper ball joint to be within the specified range...(~$500).

I am also aware that this misalignment will not affect tire-tread wear.

I contacted the dealership to investigate and was told by their alignment guru that the WJ comes from the factory with a caster alignment not within the specified Chrystler range.

IS THIS COMMON and KNOWN TO BE TRUE?

Should I spend the money to get this fixed?

What drawbacks are there from not fixing this issue?

5.5 degrees is plenty of caster, your fine if your happy with how she steers and how the steering wheel returns to center.

Thanks, I would have thought the same.

It does pull a little to the right when I let go of the steering wheel.

When the shop checked the alignment everything except the caster was OK.

Are the stock ball joints Adjustable?
(Perhaps lining them equal to 5.5 each will solve the pull?)

I dunno what that shop is talkin about, but the stock ball joints are not adjustable. Adjustable ball joints are available for the WJ however.

If you are happy with it, just leave it.

They wanted me to replace the ball joints with adjustable upper ball joints to put the caster alignment between 6.0 and 7.5 degrees; Instead of being at 5.5 degrees.

The Jeep is pulling hard right when I let go of the steering wheel.
The shop said the caster being under is causing the pull since the rest of the alignment is ok.

Basically to fix the pull he wants to replace the upper ball joints.

I am not so sure that changing the ball joints to fix the caster (within specified range) will take the pull away.

Sounds more like a caliper hanging up on the right wheel.

The caster isn't off enough to have a hard pull. Maybe a slight pull, but not a hard pull.

Sounds like you have another problem.

mine barely pulls to the right as well....I took it too an alignment shop and they said there was absolutely nothing wrong with it and it is most likely the grade of the road since they tend to slope to the right for drainage
