I'm probably going with these on my 06 soon, but am having difficulty trying to find the part numbers. I've searched on the site, but get a number of part #'s which makes it confusing. Looking for the heavy duty option (if it exists). The guy at Napa gave me a couple of part numbers:
Upper: 260-1580
Lower: 260-1579
but I don't know if they are correct, or if there are other better options. I emailed Federal/Mogul, but they didn't reply back.
Lots of BJ threads lately, I know. Thanks in advance.

Or if there is a better option that I can get access to (I'm in Canada, New Brunswick) that would be better.
Thanks again.

Rockauto.com has ACDELCO, Spicer and Moog. The moogs are adjustable. The others are straight replacements. all greaseable.

With the adjustable ones, is this an advantage over anything, can they be installed at a default? Just wondering what I would get out of that. My truck is stock suspension.

How many miles before I should expect ball joints to be bad?

GreyTD

The adjustable are good if you are having alignment issues. I don't see any other advantage. I went with spicers.

Country23047 --You can check your ball joints any time you want. Jackup one side, using a long pry bar, put under wheel and lift, watch for movement up/down on lower joint. Nice tight joints don't move, oem have slight movement, but still should be less than 1/8" IMO. Upper joint while tire still in air grab tire at 12 and 6 and rock in and out, should not have move.

I changed mine out at about 80,000 miles and installed the Napa ones. I dont have a part number but as far as what they look like compared to the Spicer brand they are a way better product.

My two sets of OEMs have started to wander noticeably after 35,000 miles. Time for aftermarket.

I have had good luck with moog and have agood warranty and always get greasable. upper ball joint $ 70 lower $82

Give Dynatrac a call, they are starting to build a greesable and rebuildable ball joint.
