Title: u joint question
Post by: jcondo on October 08, 2018, 06:54:04 PM

Did they use 2 different u joints on the front axle in 77 K10?
passenger side went together just fine with a 371 u joint, but the driver side wont go flush and wont slide into the hub casing if they are not flush.
Thanks for any info.

Are we talking the inner to outer shafts U-joints.  They "should" match.

They were the same on my '78.

Check the build date; was it on a Friday after 3pm? Those '70's were wild! :>)
