2000 Jeep Cherokee - Vibration between 50mph and 55mph (about)

sounds like a tire is unbalanced.
make sure a weight has not fallen off.

mr> through it or slow down steadily through it.

mr> My inaction is from lack of trust in the mechanic who did the ball
mr> joint work and the lack of funds I'll need in case it's a huge job.

mr> Now, my reading has led me to have hopes that it's simply a matter of a
mr> possible weight fallen off a tire or a wheel out of balance for another
mr> reason. Is there anything else I should consider? I need to get this
mr> taken care of.

mr> The vehicle seems fine except for this. Sometimes the vibration
mr> doesn't seem that bad, other times it seems like the wheels are falling
mr> off.
