While driving, the bearing allows the drive shaft some flexibility; however, if there is too much flex due to a worn bearing, the vehicle may start to have problems. Ignoring this problem can damage the differential, transmission, and the driveshaft in your vehicle.

Using a plastic hammer gently shock the driveshaft loose from the differential flange by striking the rear yoke (U joint mount). At this point the back half of the shaft will be free so hang onto it. On some cars there will be a center support which must be undone by removing the two center support mounting bolts.

Rule №1 Always hook the care from the rear. Rule №2 If you can’t hook it from the rear, remove the driveshaft before towing from the front. Rule №3 If you can’t hook from the rear, or remove the driveshaft, then remove the axle (or axles). Once the axles are removed you can hook from the front.

The average cost for carrier bearing replacement is between $322 and $357. Labor costs are estimated between $132 and $167 while parts are priced at $190. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

The cost to replace an input shaft bearing may range from $200 to $300. The part itself only costs about $25 to $75, depending on the make and model of your vehicle. But the labor costs will be much more because it’ll take the auto mechanic more time and effort to get to the input shaft bearing.

An excessively worn or faulty center support bearing will howl or squeal when the vehicle accelerates from a stop. The howling or squealing may quiet down as the vehicle picks up speed.

Over time, the center support bearing can become worn due to it being used constantly. When this happens, the vehicle starts to shake when you accelerate from a complete stop. The shaking will cause strain on the drivetrain components and your vehicle will not be as responsive when turning as it once was before.

CC: How much should the front yoke of a driveshaft engage the output shaft of the transmission? DD: The slip yoke should be able to go into the tailshaft of the transmission so the barrel is fully inside the seal. Then, pull out the yoke 1 inch. This is the correct amount of spline contact for the slip yoke.

The slip yoke is an important component of any drive shaft assembly. The slip yoke assembly (pictured on the right) is what allows drive shafts and PTOs to flex or “slip” with their given application. The slip yoke is also essential for allowing u-joints to rotate properly with the drive shaft.

A car with a bad U-joint will break down in a few hundred miles at the maximum. But if you have a bad U-joint and you are having a transmission fluid leakage, you should not drive your car since the U-joint may break down anytime and will cause damage to the brake line, drive shaft, transmission line and other parts.

The u-joint replacement cost is estimated between $225 and $300. Labor makes up about $100 to $125, while the parts should be between $125 and $200.
