After the front u-joint went out last week I got the trike back with a new u-joints and an new drive shaft (u-joint bent the ear so we decided to put a whole new system in). Didn't realize how much slack there was in the old unit. Trike feels so tight now as I shift and accelerate and decelerate. Should have changed this a long time ago. Just glad there was no other damage as I have seen on other u-joint failures.
