Can a loose U-bolt cause rear axle to shift?

When the rubber pads deteriorate, or just squash and settle a little thinner with time, the U-bolts can become a little loose. This allows the rear axle to shift fore or aft a little on the leaf spring with acceleration and deceleration.

What happens when the rear differential goes out while driving?

Depending on the vehicle and the issue the rear differential has, what happens when the rear differential goes out while driving varies in severity. If you have broken gear teeth or badly chipped teeth then you will experience a soft of “skip” in power or vibration that increases with speed.

Why do you need a differential in the middle of a drive axle?

Two wheels on a drive axle without a differential in the middle would result in both wheels receiving the same power at all times. Having a differential however, enables each wheel to act individually. Why should you care?

Why is my rear differential Howling under acceleration?

Howling under acceleration at various speeds, however, indicates that the gears are already worn out or are out of alignment or depth with each other. If rear differential noise occurs while accelerating the car only at a certain speed, it is likely because the gears have become worn due to overloading and lubrication failure.

What should I do if my rear differential is making noise?

Drives is advised to pull over in order to prevent the possibility of loosing control. Having teeth affected on a single pinion gear may not ruin your differential completely and if caught in time you might be able to slowly reach a mechanic shop without a platform. If there are more broken teeth on a ring or pinion also, then that’s another deal.
