Someone school me on the different sizes or types or u-joints on these trucks.

My truck is a 1996 F250 and the u-joints had straps that bolted to the yoke.

The used axle I bought was SUPPOSED to be from a 1995 and appeared to have a smaller yoke that uses u-bolts to secure the u-joints to the yoke.

I had to leave the shop since the alarm arms at 8:00 so I didn't have time to investigate much further. Do I just need to get the u-bolts or do some trucks use a smaller u-joint??

TIA!

 

I swapped axles between a 95 and 96 and they were the same except the transfer case yoke. I took care of that and bolted it right back up with the straps. The front drive shaft on mine had the small u bolts though. Not much help u know but a little info anyway

 

looks like I may have found my answer, 331 and 434 u joints are used in the rear... One with straps, the other with u-bolts. Now I have to see if anyone makes a 331/434 combo joint.

 

At least from 86 on I believe were all caps on the rear ends. U bolts on the fronts. IIRC

 

Have you tried changing the yokes. I think the pinion shaft on both should be the same.

 

Thats where I'm at right now... The yoke off the old rear axle is in the hotsy right now getting warm!

 

Napa has the combo U-Joint that you are looking for. It's about $40.00
