How many U-joints does a 1978 toyota pickup have?

Asked by Jun 16, 2013 at 04:33 PM

Question type: Maintenance & Repair

This is actually a small RV built on an SR5 pickup, but i'm assuming the truck is just like any other SR5 when it comes to u-joints.  It is making a clunking sound that accellerates as the truck accellerates, and we've been told it's either a u-joint or the rear axel.  Any thoughts?
Thanks!

Has the frame been stretched? If it has there might be a support bearing on the drive line so it may have 2 shafts not just one. so 4 u- joints instead of 2. Check that carrier bearing for excessive play as it may be bad also. The rear ends are not very strong on this type of conversion so check for excessive slop in the ring and pinion.
