U-Joint

» Do you hear “squeaks” near your rear axle or wheels when you drive at low speeds?
» Do you hear a “clunk” when stopping your vehicle?
» Do you feel a vibration when you drive at high speeds?

These symptoms could mean a worn or dry U-joint. Fix this problem as soon as possible. If you don’t, your driveshaft could soon drop to the pavement.

Universal Joint (U-Joint) Basics

Most drive shafts feature two universal joints. Often called U-joints, these cross-shaped pivots are situated at either end of your drive shaft (assuming a rear-wheel-drive vehicle).

U-joints flex in two different directions. Flexion takes stress off the drive shaft. U-joints allow drive shafts to move freely and operate at many different angles–without affecting the rigid transmission shaft. U-joints also absorb the movement of the axle and wheels.

Types of U-Joints

Cross-and-roller U-joint:
Also called a Cardan’s joint or Hooke’s joint, this is the standard U-joint for rear-wheel drive and four-wheel drive vehicles.

Constant velocity U-joint:
CV joints, as they’re usually called, eliminate velocity changes caused by changes in drive angle. CV joints can transfer power through very sharp angles (up to 40-degree angles). CV joints are generally used on front-wheel- drive vehicles, although newer real-wheel-drive vehicles with independent rear suspensions also use CV joints.

Causes of wear to U-joints

Lack of lubrication
Idling at higher speeds
Excessive drive angle
Rough, abusive driving
Water exposure to joint

During our Cross-and-Roller U-joint service, we check for:

Looseness around roller cups
Rust stains around roller cups
Loose or warn joints (which causes vibration at high speeds and clanking sounds when in gear)

During our CV joint service, we drive the vehicle and listen for:

Low-frequency humming (suggests poor lubrication of joint)
Steady knocking sounds at low speeds while driving on straightaway
Popping or clicking sound with sharp turns at slow speeds
Moderate to severe side-to-side shaking on acceleration

We also perform a visual inspection on your CV joints. We:

Check inner and outer CV boots
Open folds of boots and look for cracks
Inspect boot clamps
Check driveshaft for damage
Check CV joints for looseness

Driveline Analysis

Today’s customers set high expectations for automotive refinement in terms of noise, vibration, hardness and sound quality (NVH). The driveline of a vehicle is often named as the source of many NVH issues.

If you have NVH problems in your driveline, it can be infuriating and frustrating to try to pinpoint and correct them. You may spend hundreds, even thousands, in replacing parts, only to end up with the same problems you started with.

Let Vancouver Axle and Frame diagnose and repair your driveline RIGHT THE FIRST TIME. Our advanced diagnostic equipment and our years of experience will save you time and money and get you back on the road fast. When other shops are stumped, they trust us to fix their driveline problems RIGHT…you can trust us to fix yours, too.
