I am doing the passenger side ball joints and hub assembly this coming weekend so I bought a new one from Auto Zone for $167 and thought I'd share some pics. Look real nice and came with the studs and yellow o-ring as well. Too bad they stapled through the o-ring and broke it.

 

I'd advise against doing just one side too. In order to do it right, you should get an alignment after replacing a ball joint(s). Save up and do it all at once, then get it aligned.

 

The driver side has a new hub assembly, OEM locking hub, axle u-joint and ball joints. Now it's the other sides turn.

 

You probably won't need to align it. Where are you going to get a new O- ring now?

 

I was just looking at doing the passenger side on mine and use the timken one also. My drivers was replaced in summer of 2010 from an accident I was in. When I had it apart doing a brake job, I noticed that the passenger one doesn't wanna roll near as easy as the drivers one does. I think I can feel it sometimes when I take off from a stop sign or red light. Feels like a slight " hesitation" or something before the truck wants to move. Very little and only sometimes though.

 

Since yours is a 2001, what thread pitch did you order? Mine is an 04, and I took one of my lugnuts to advance and it threaded right onto the 14x 1.5 . I thought the 1.5 was the coarser of the 2, compared to the 2.0 and I thought after a certain year they changed to the finer thread?

 

They changed to fine about 02?. Look on ebay to get the specs

 

14x1.5 is fine thread, 14x2.0 is coarse thread.

 

Cool. Thanks Digger!!
