What should my front pinion angle be?
5 to 5.5 degrees or higher is normally enough, with larger tires not needing as much caster angle for good return-to-center as smaller tires do.
What is the proper driveline angle?
Driveline angles should be equal to or within 1° of each other. When checking driveshaft angles, be sure all tires are inflated to their normal operating pressure.
What should the pinion angle be on a jeep?
Unfortunatley, our world isn’t perfect and the needle bearings inside a U-joint need to move to stay lubricated. The pinion angle must be 2 degrees below the drive shaft in to cause the needles to move and be lubricated.
How to calculate the pinion angle of a car?
If the angle of the rearend is steeper than that of the driveshaft, subtract the angle of the driveshaft from that of the rearend to see how much positive pinion angle you have. For example, if you have a rearend angle of 5 degrees from vertical nose up and the driveshaft is angled up at 3 degrees,…
What should the pinion angle be on a ladder bar?
A ladder bar or 4-link setup is much more rigid and therefore usually only needs 1-3 degrees. You never want the rearend setup with positive pinion angle. This is when the yoke of the rearend is tilted upward more than the driveshaft.
What happens if your pinion angle is wrong?
You, your 4×4, and Access… Pinion angle is one of the more important measuerments on a lifted vehicle. The wrong angle can lead to drive line vibration and premature failure of U-joints, drive shafts, pinion bearings and even transfer case output bearings.
How to set pinion angle on Jeep Wrangler?
With the Jeep sitting at on the ground at ride height we can now set our pinion angle. The upper arms need to be lengthened slightly in order to rotate the rear axle pinion up. Since my Wrangler is equipt with a CV driveshaft and has coil springs you want the angle of the driveshaft to be the exact same angle as the axle yoke.
How do you install control arms on a wrangler?
Some people can eyeball the correct angles, if not use a angle finder. With the pinion angle correct make the upper arms the right length to hold that angle then your good to install them. Double check to make sure any bolts removed are torqued to the correct specs for your year Wrangler and grease any fittings necessary.
What’s the best way to adjust the pinion angle?
The correct way to adjust pinion angle will vary from vehicle to vehicle. Leaf spring equipped vehicles can use wedge shaped shims for quick adjustments, but a more permanent fix is to remove the spring perches and weld them on again at the correct angle. The adjustment is normally even easier on coil sprung, solid axle equippped vehicles.
How to install control arms and set rear pinion?
The same as all the other arms, 2 bolts holding in the arms and the uppers can be removed with a 15mm socket. However, this time we removed both arms and lowered the Jeep off the lift. With the Jeep sitting at on the ground at ride height we can now set our pinion angle.
