Like others out there have posted recently, I too rolled down my window a week ago and heard a clicking sound. Sure enough, the right front U-joint is shot.
I read the links and thanks to those of you who posted info. I'm far from a mechanic but can't stand the thought of going to a dealer. You guys give me enough courage to try it in the driveway.
My first challenge was figuring out what differential I had. I've decided it's a DANA 60 because it has a 60F stamped on it in the lower R when viewed from front of truck. Then I had to figure out if I had a 3500 or 4500 lb axle. According to the tag in the door, I think it's 4500 lbs. The repair manual is not much help with either of these. Someone let me know if I've already screwed up.
Now for the question. Several of you recommended getting a replacement u-joint with zerks from NAPA. Sounded like a good idea. Unfortunately, the NAPA in my neck of the woods says it's not available for the 4500lb axle. He said it is available for the 3500lb axle. Here is the part number he sold me. It's a Spicer by DANA and so is the original equip. The number on the box that looks like a factory number is 5-332X. The number stamped on the part is A4 with 857 below the A4. They had another brand. I think it started with a P. It didn't come with zerks either and they said the Spicer is a better one. What are you guys using?? Tell me if I've gone astray, please.
Tomorrow I'm going to attempt to get this thing apart. After reading the other posts I think I have all the tools but know it will be a challenge. I picked up new ball joints as well and will have to take the assy in to have the old one pressed out and the new ones pressed in. I don't have tools for that and it seems they cost lots of $$$. Hopefully it won't cost much or take long to have it done. NAPA said they could do it in their shop.
Sorry for the long post. Any advice will be appreciated. You guys are going to make a mechanic out of me yet.
See my signature for year and model info. If this goes resembly well, I will try the other side. I'd like to get past this so I can add some gauges and then start bombing.
