Universal joints allow drive shafts to move up and down with the suspension while the shaft is moving so power can be transmitted when the drive shaft isn’t in a straight line between the transmission and drive wheels. Rear-wheel-drive vehicles have universal joints (or U-joints) at both ends of the drive shaft.
Universal joints, being a heavy-duty component in off-road and rear wheel drive vehicles, can undergo many issues that lead to its failure. These can severely affect the movement of the vehicle and can cause great losses in the rotational power and torque transmitted from the engine to the wheels.
A bad u-joint can cause a clunking sound or jerkiness while driving, particularly when letting off of and pressing the accelerator. A bad u-joint can also cause vibration at certain speeds, emanating from the center or rear of the vehicle. … Then, shift into drive.
The average price for the u joint replacement cost ranges between $190 and $260 for the replacement, while the labor on this job runs between $170 and $210 on aveage, with the parts ranging between $20 and $50. Keep in mind, the average u joint replacement cost will vary depending on the type of vehicle you have.
U-joints can last decades, or they can break when the vehicle is still new. That’s why it’s a good idea to check the u-joints at every oil change. A typical rear wheel drive vehicle has 2 or 3 u-joints. Some vehicles with a long wheel base, such as buses, have 3 or more u-joints.
On a typical labor book, a U-joint replacement is one or two labor hours, meaning that a $25 part can cost substantially more once someone else installs it for you and charges around $100/hour.
Drive line vibration, after u-joint replacement, is usually the result of a u-joint not properly posi- tioned, or yoke ears which are binding. In either case the problem can usually be pin pointed by articulating the drive shaft. … The replacement u-joint, even though centered, could cause the shaft to vibrate.
A broken driveshaft can prevent wheels from turning properly, giving you trouble when trying to make turns. This issue limits your overall control of the car. You need any issues that prevent you from driving the car correctly addressed right away for safe driving and continued use of the vehicle.
NOTE: The u-joint must be greased prior to installation. There is only enough grease in a new MOOG u-joint to keep the needles in place during assembly, which is not sufficient for operational lubrication. Before installation, there are three steps to follow to ensure long service life: 1.
This is basically a joint with two u-joints. U-joint maintenance isn’t too much of a factor today for the occasional off-road enthusiast. Most over-the-counter u-joints are sealed and nongreaseable and require little maintenance.
Universal joint is a joint in a rigid rod that permits. the rod to move up and down while spinning in order to. transmit power by changing the angle between the. transmission output shaft and the drive shaft.
Squeaking noise when starting to move (forward or reverse)
The bearing becomes dry, metal-to-metal contact is made, and the u-joint bearings will squeak as the drive shaft rotates.
There is no such thing as greasing a u-joint too much. If you don’t like the grease getting all over the frame, make yourself a splatter shield out of sheet metal.
If you allow the driveshaft to die completely, then it will reach the point where the wheels no longer receive any power. While there is no set lifespan of a driveshaft, it typically can last about 75,000 miles. Keep in mind depending on the vehicle, and wear and tear you may get much less or much more.
Replacing these joints is a fairly straightforward job, though it takes some prior experience. To begin, you’ll need a universal joint pressing tool. You can also take advantage of the loaner tools program at your local Advance Auto Parts store. Then follow these step-by-step instructions on how to change U joints.
Usually, the Drive Shaft Repair costs will differ based on what caused the issue and how fast it can be repaired. If you just have to replace it, that would be anywhere from $500 to $1000. However, you can also expect the cost of the parts to be around half that number and the labor costs around $200.
From what we researched via multiple quotes online, the average driveshaft balancing, including professional labor, tends to be in the $120 to $185. However, if you needed new U-joints, as well as the driveshaft balancing, which is often the case in most repairs, the price can be closer to $200 to $250+.
WD40 isn’t a lubricant and shouldn’t be used as one. It will actually take good oil away from moving parts. Use spray silicone or a light oil for bearings and joints..
Rear-wheel-drive vehicles have universal joints (or U-joints) at both ends of the drive shaft. … Front-drive vehicles also use two joints, called constant velocity (or CV) joints, but they are a different kind that also compensate for steering changes.
