Axle u joint question

[ColoradoColt]

So getting the driver side axle u joint done today. I did the passenger side about 6 months ago and everything went fine. So here’s where I need help. I watched a few videos and read a few articles on the driver side, and some people have said that if it’s 4wd you have to lock it in 4 so that something doesn’t drop in the diff when you pull the axle shaft? Is there any truth to this or can I just do it the same as the passenger side? Also does anyone seem to have a part number for the driver side u joint? Autozone gave me too small of one already which I remember they did last time so I had to bring in my old one to compare. Today I don’t have another Vehicle to go back if they get me the wrong one again so any help on that is very appreciated.

They were both the same on my 02. I just pulled both my shafts and replaced the ujoints. I have not heard of anything that would fall into the diff. Lets see what some others might say in reference to that.

I think  if you're have a cad axle then the ring that locks it in needs to be in certain position or it can fall off, then you'll need to open the cover and put it on. You're on driver side so should be fine, I don't remember doing anything special when I changed mine aside from the cad part. I got original spicers from local rebuilder, I believe they get better quality parts as they do it for a living.

I have pulled both front axles from mine at least 3 times over the 19 years l have had it with no issues and it has the CAD axle. Juat dont use abnormal force reinstalling them, they should go in easily. They both have to go thru a seal to be reinstalled and you dont want to booger them up.

Since I don't know if you have a 2500 or 3500 and what GVWR rating is of your pickup, this is what I can provide;

Autozone sucks! They don't even seem to know what u-joint is when looking up a search for it.

 Awesome thanks I can pick one up from them on my way home. Autozone didn’t have any dimensions for them and the last one I bought for the passenger side was moog for 75$. I noticed the Spicer one is only 60$
