    Comments about Moog Driveline Products U Joint:

    I've been a mechanic for over 35 years. I have replaced literally more universal joints than I could count. I have used Moog u-joints in the past with no problems. Now, I've seen old u-joint caps fracture and break off while being pressed out many times. It's not a surprise when they are old and weak from constant stress. This is the FIRST time I have ever seen a u-joint cap fracture and blast off like a bullet while pressing it in when brand new however!!! Upon looking at the broken cap I realized the metal is very porous and light. It appears to be nothing more than cheap die cast "white metal" as we used to call it.

    Completely worthless. In fact, I'm going to press out the one that did NOT break and return both of these. "Super strength" my hind end! I'd hate to have managed to get it in without breaking it only to have it fail on the road.

      A axle ujoint that you can greese.
      Lilving in a state where magchloride is used you need to be able to greese ujoints to push out that stuff and keep the needle bearings lubed.

            Great part at a great price. Easy to install. Fit my Jeep perfectly. I will never pay a professional mechanic to install another U-Joint.

                I like that Taneytown usually has the parts I need. This piece fit nice. Good warrantee. Having a grease fitting is a real plus for a 4x4. Time will tell how good it truly is.Moog generally makes an excellent product.

                    Hi Chris, happy to help you! It is always recommended to change both driver and passenger side universal joints at once. However, I would suggest that you to take your
                    vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.
