Clunking sound, when going from acceleration to deceleration or deceleration to acceleration, may be caused by slip yoke problems. The splines may be worn. The yoke transmission extension housing bushing may also be worn. This will let the yoke move up and down with changes in drive line torque.
What causes slip yoke clunk?
A binding of the slip yoke on the transmission tail shaft can produce a “clunk” sound on these vehi- cles. ... When vehicle movement is begun, the slip yoke can pop forward releasing built up tension and causing a “clunk” noise in the drive line. This noise may be mis-diagnosed as a universal joint or spring problem.

Generally speaking, a bad drive shaft is going to create a kind of rattling or clunking sound . You may also hear sounds that are like a high-pitched squeaking or a scraping noise of metal on metal. All of this will originate from underneath your car, rather than in the engine compartment.
How far does a slip yoke go into 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.
How much play should a slip yoke have?
For safe and stable operation, the slip yoke and spline should maintain at least 2 inches of engagement at all times .
What does a bad slip yoke sound like?

What does a bad drive shaft look like?
Common signs include intense car vibrations and abnormal noises , like clunking, rattling, and scraping, coming from under the vehicle.
What does slip yoke eliminator do?
This sliding capability allows for changing length depending on the vehicle's movements. A slip yoke eliminator, abbreviated SYE, does what the name suggests: It eliminates the slip yoke from the transfer case . Instead, it turns it into a fixed yoke that does not slide.
Why does my truck clunk when I accelerate?
The most likely causes would be low transmission fluid, a shift solenoid, transmission mounts, or a drive shaft . Your best bet may be to have a qualified professional, such as one from YourMechanic, take a look at the car in person in order to diagnose and repair your acceleration issue.
What is driveline clunk?
A clunk, whine, or howl can signal a worn-out pinion gear, bad bearings, or a faulty gear installation . Sometimes, the noise is not differential-related, but is caused by other driveline or axle components.
How do you measure a slip yoke?
Place one end of the tape measure near the tip of the slip yoke. Place the other end of the tape measure near the middle of the slip yoke's u-joint. Note the measurement on the tape measure to determine the length of the slip yoke.
What is a slip yoke on a truck?
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.
What is a 1310 U joint?
1310 U-Joint Series is the most common U-Joint ever used . It is still used on OE applications. 1.062 cap and 3.219 width. ( 1 1/16 x 3 1/4 close) 1330 U-Joint Series is very common and used on OE production.
What is a bad slip yoke?
Clunking sound, when going from acceleration to deceleration or deceleration to acceleration, may be caused by slip yoke problems. The splines may be worn. The yoke transmission extension housing bushing may also be worn. This will let the yoke move up and down with changes in drive line torque.
How much does it cost to replace a driveshaft?
On average, you can expect to pay anywhere from $400 to $1,260 total but it can easily approach close to $2,000 for some vehicles. If you have a four-wheel drive vehicle, you may have two driveshafts but in most cases, only one will need to be replaced.
