Why does the back end of my car wobble when I hit a bump?

Why does the back end of my car wobble when I hit a bump?

Generally, several vehicle conditions can cause vibrations, from worn suspension parts to brakes and transmissions to tires. If you feel a fast, vibrating shimmy, hitting the bump may have knocked your vehicle’s weight off, and now a tire is out of balance. Either way, now your vehicle’s parts are out of sync.

Why is my rear end shaking?

Balance. One of the main problems that can occur with the rear end of a truck is balance problems. When the truck is driven over uneven ground or on roads with potholes, the alignment of the tires is altered. This can cause the truck to vibrate and shake in the back end if the truck’s back axle is misaligned.

Do I need an alignment after replacing upper ball joints?

Yes, when you do any major work to the front suspension, you need to have the alignment done. Even though the parts are “basically” the same, they are not exact. Newer parts will be tighter than old (less deflection and no wear), so will put the alignment into a different position.

How many hours does it take to replace upper and lower ball joints?

It can take a little over an hour to get it replaced, so the full ball joint replacement cost will be between $100 and $400. You never know how much the mechanic is going to charge you until you get the replacement done, but it can help to have an estimate beforehand.

Do ball joints go bad at the same time?

If you change the ball joints due to wear on one side of the vehicle, then the other side will likely go bad in a short time. I would recommend replacing both sides at the same time so only one alignment needs to be done and you have the peace of mind that your front ball joints will be good for a long time.

What happens if a ball joint fails while driving?

A broken ball joint may be the cause of a mysterious clunking noise or drifting steering. And once they’re worn, they will seriously affect your steering and suspension. If a ball joint fails completely, it can even result in the wheel dramatically falling off the car.
