I went to my local auto parts store to get U-joints for my 2wd 98 ranger.
It seems for one of the u-joints there are 2 possible sizes. One has all cups the same size, the other has 2 cups slightly larger than the other.... (and likely not that visible to the naked eye from the dimensions I saw in the catalogue)

Is there a way to tell? Maybe a code on the driveshaft or something?
I was hoping to have the right part BEFORE I start the work....

 

custom made ones from a metal shop took 5 mins cost 40 bucks came with hardware

find out axle tube diameter, and length

 

U joints not Ubolts...

Your should be able to look up the ujoints on their computer system. maybe someone who knows what size you need will chime in.

 

idk what ones you need, but you should get some brute force's or dana spicers.

 

Not really sure what brands they carried... wondering if the Napa ones are ok.... or are at least as good as the original ones that are on there now.

I did get them to look up in the computer system, in 2 stores, and each one told me I have 2 to choose from. One having all 4 cups the same size, the other has 2 cups one size and 2 cups another size.... don't know which one I need, or how to tell without having the truck disabled first.

 

haha ok it was like 4 30 in the morning when i made the post..so im sorry read it wrong..

 

Brute Force are crap... I had a set take a dump on me within a month of installing them.

Spicer are some of the best if you can find them.

Napa brand joints are pretty good too. That is what I'm running now and haven't had an issue.
