Loud clank, truck wont move now..
Left work and about a mile down the road, at
about 35-40mph I heard a loud bang, some
clanking, then lot of resistance from the rear
tires and occasionally tire squeal.. Pulled
over, U-Joint is tight and in fair condition..
Truck won't move in any gear forward or
reverse. Cannot push it in neutral. Hooked
up a tow rope and heard clanking for a
second till it started rolling. How can I
trouble shoot if it's the transmission or the
rear end? 97 Tahoe/4L60e
