Volvo 760 Universal Joint Replacement Cost
How Much Does a Universal Joint Replacement Cost?
Universal Joint Replacement Service and Cost
A universal joint is a joint that is bolted or welded onto a shaft, and allows that shaft to rotate, even when bending. In rear wheel drive and four-wheel drive vehicles, they allow the suspension to travel without breaking the drive shaft.
By attaching a four-way hinge between two shafts, the two shafts can move independently of one another, in all directions, and the power from one of the shaft can be transferred to the other end of the shaft, even while the shaft is bent. This allows the drive shaft, and some axles, to connect two components that are not in fixed positions relative to each other.
Commonly, vibrations that increase with vehicle speed, and a rapid chirping noise are very evident when a universal joint (U-joint) fails. The chirping and vibration may change intensity as the vehicle passes over bumps in the road. As the problem progresses, the drive shaft may make a loud clunk anytime the vehicle is put into reverse or drive. Vibrations, and wobbling will eventually lead to leaky seals on the transmission tail shaft, or transfer case. When the U-joint has reached total failure, it may bind and break, which can allow the drive shaft to fall off the vehicle while driving.
It is not recommended to drive with a failing universal joint. Every time the universal joint squeaks, is a chance it can bind and break. If driving the vehicle must be done, slow speeds and light acceleration are recommended. The universal joint should not be left unattended and in operation for any extended period of time, as failure will occur, and damage to the vehicle is possible.
Universal joints can have a lengthy service life if properly maintained, and 100,000 miles is not at all unreasonable to expect. U-joints to fail prematurely, most commonly as a result of vehicle abuse, collisions, lack of maintenance, and dry-rot of the rubber lip seal.
Universal Joint Replacement Repair Information
When a U-joint is making noise, the entire driveline must be inspected to determine the noisy joint. The noisy universal joint will feel loose compared to the others, and may even have visible movement. The transmission or transfer case seal nearest the U-joint may also be leaking, and the carrier bearing, if equipped, may be worn.
The faulty universal joint is replaced as an individual component, or by replacing the entire drive shaft. Vehicles with non-serviceable universal joints will require driveshaft replacement. Serviceable u-joints require removing retaining clips, and sliding one side of the joint out of the yokes at a time. The new universal joint slips in, and is help by retaining clips. If the transmission of transfer case seal requires replacement, the drive shaft is easily removed, and installed.
We recommend using OEM quality or better when selecting universal joints. These parts tend to be inexpensive, and are vital to the smooth operation of your vehicle. Purchasing low quality universal joints may lead to repeating this repair.
If the universal joint binds and breaks, when it falls from the transmission, transmission fluid will be lost quickly from the tail shaft, and the engine will rev higher than expected. This can result in transmission damage, and can be prevented by repairing the issue soon after it is noticed.
Universal joint replacement can be accomplished with a few tools, and a little mechanical experience. If removal and installation procedures of a universal joint are not followed strictly, damage to the needle bearings may lead to failure. If the U-joint requires replacement of the entire drive shaft, a professional service may be able to replace only the universal joint to save parts costs.
