My brothers '76 just got back on the road and we noticed a rather loud clunking noise behind the drivers seat. Sounds like the drive axle u joint is bad.
I raised up the rear and slightly rotated the tire/wheel to look for play and noticed some.
My question is, how hard is it to replace these u joints? Does anyone have some good instructions or is it straight forward. Do we replace both sides at the same time?
Are you sure it's a u-joint and not the front rubber bushing for the differential? If it is worn out it will clunk when you start forward, backward or when shifting. Hope this helps.
