what brand of u joints u running in the reatr shaft on a 03 shorty 4x4 . time for some new ones thanks robbie

 

Spicers are a good choice.

 

I have greaseable Spicers in the front of my truck and love them. When I had to replace my stock rears, Spicer did not have them available yet.

 

I just installed Precision 330A greaseable u-joints on my rear driveshaft last week. I believe your 6-speed will take 351A precisions on the rear driveshaft. Here are some pics of the original u-joints:

 

thanks surfram. going to get the per at napa 33 bucks i think thats what they said it was 351a .thanks rob

 

FWIW,

The only place I could find them "made in the USA" was from napa....



Go figure...

 

I hope you have better luck with yours then I did... I could not find a u-joint to actually fit my shafts... Everyone of them I tried was about .100" to long and would not let me put the retaining clips in without placing a extreme amount of pressure on the joint and ears. Something that should have taken an hour, took me more then a day running around to autoparts stores and measuring what they had in stock. I can not see how to make the "called for" joints work without grinding them down alittle bit on the ends, but thats where you get into a "out of balance" issue...

Long story short, I forced the joints in but they are extremely tight, took alot of pressure from my hydro press. I now have a slight viberation at about 70mph... I am to the point dropping the cash and just having a driveshaft shop redo it and balance it out..

Before its asked, I put u-joints in my jeeps and other vehicles all the time. So it's not a lack of experience thing... It's like the retaining groves where machined to far into the ears or not wide enough...

 

thank asher i let every one know how it turnns out . going to my friends meching shop to do it. should not take long and i'll have every mechine known to man to use if i have problems.

 

asher, the only ones that will truly fit are the aam joint, i knew that when replacing mine, i used spicer 160x they also r .100 too big, the clips are a little bowed out but have been in for over a year now with no issues, all you have to do is grind or belt sand the caps down slightly, for a perfect fit. I allways mark a line down the shaft so everything goes out and in the way it was originally installed

 

The precision 330A and 351A are designed for AAM driveshafts. Mine fit perfectly.

 

i just put in a pair of sealed spicers 1410x using the std. hammer and sockets routine and they fit perfect.. dunno
