I have had alot of problems with ball joints!! About 4 years ago I went in to get an alignment for abnormal tire wear and found that the upper and lower joints were shot. They replaced all the joints,
Note: the upper joints are threaded in NOT pressed.
and a year later I had the same problem. This was the NAPA parts and they replaced them free of charge. Another year later they were shot, mostly the uppers

, the uppers shouldn't wear as they only hold the wheel vertical!!!. Now they replaced them with MOOG heavy duty balls, and an upper a-arm as one of the balls popped out
#ad
, fortunately no injuries
#ad
. It has been about 2 years with no noticable wear.
I blame most of this on having the "red-headed stepchild" of diesels in the Dodge. The books don't have alot of info on the 89 trucks, some say diesel some don't. Make sure that they get the heavy duty version of balls, especially in your 1 ton. I can get the part numbers of all the balls etc if you need this info, but I assume that yours are going to be different.
