Is the drive shaft supposed to spin?
Neither of your driveshafts should be spinning if you’re laying under the vehicle- unless its suspended or something. Otherwise the driveshaft spins when the front axle does- the connection to your drivetrain occurs in the transfer case and does not engage until you move the corresponding shift lever.
How do you know if your drive shaft has gone?
A common symptom of a failing driveshaft is an intense shaking coming from underneath the vehicle. Worn out u-joints, couplers or carrier bearings can cause the driveshaft to vibrate. If you don’t get these components serviced, it can lead to further damage to other drivetrain components.
Should my rear drive shaft spin freely?
A little bit of rotational play like you describe in the rear driveshaft is fairly normal. When in 2wd, the front spinning freely is also normal due to the front axle disconnect as said above.
Does a driveshaft spin in neutral?
Registered. If you turn the input shaft on a transmission while in neutral, even without any lubricant (or the transmission in a vise out of the case), the output shaft will turn just due to friction between the parts.
What happens when your drive shaft goes bad?
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.
Should you turn a drive shaft by hand?
So, yes, you should be able to rotate the driveshaft by turning the wheel. However, with that said, I personally would get under the car and rotate the DS by hand to visually examine the DS and center mount, Joints, etc. There will be a front and rear Ujoint for each half of the driveshaft with a center bushing.
Does the driveshaft spin when in neutral?
Where are the gears on a Toyota 4Runner?
While it shares internals with the V6 diff, the gears are unique to the High Pinion due to the reverse cut, which puts the gears on the drive side of the teeth in the front axle. High pinion diffs are commonly found in 1990-1997 FJ-80 and FJZ-80 model Landcruisers that had the solid front axles.
How many revolutions does a Toyota 4Runner take?
If you have a limited slip or automatic locker, then you’ll need both wheels in the air and you’ll use just one wheel revolution to get the rear ratio. For better accuracy, you can use say 10 (or 20) revolutions and then divide your drive shaft revolutions to get the gear ratio.
Why does my Toyota 4Runner have a high pinion diff?
High pinion diffs are commonly found in 1990-1997 FJ-80 and FJZ-80 model Landcruisers that had the solid front axles. Ironically, the high pinion diff was not designed for the added ground clearance, but rather so that the steering tie rod on the FJ-80 could be run *below* the front driveshaft to keep the vehicle low!
How can you tell if the differential is out on a Toyota 4Runner?
However, if you have an axle/differential off of an unknown vehicle or it has aftermarket gears, then you’ll need to determine the ratio. If the differential is out, count the ring and pinion gear teeth (or that data is often stamped into the ring gear).
