What makes a car squeak when the lubrication wears out?
Most cars and light trucks today are manufactured with sealed “lubed for life” ball joints, tie rod ends and even U-joints. It’s a self-fulfilling prophecy–when the factory-fill grease dries out, the joint wears out.
Where are grease fittings on front wheel drive car?
You may find fittings on tie rod ends, upper and lower ball joints, sway-bar links and control-arm pivots, so hunt around and make sure to hit them all. There might be grease fittings on as many as three U-joints on the driveshaft (or shafts), depending on whether you have a front-wheel-drive, rear-wheel-drive or four-wheel-drive vehicle.
Why is my u-joint making a squeaking noise?
Squeaking noise when starting to move (forward or reverse) The bearing components of each universal joint are greased at the factory, but may not have a grease fitting to allow further lubrication after the vehicle is put into use, limiting their service life.
What causes the U-joint of a drive shaft to squeak?
Since the bearing portion of each universal joint twists a small amount with each rotation of the driveshaft (but always in the same location) the grease can evaporate, or be thrown out of the bearing cup. The bearing becomes dry, metal-to-metal contact is made, and the u-joint bearings will squeak as the drive shaft rotates.

How do you get grease into a Zerk fitting?
If there is still no grease moving you can use a propane torch to heat up the zerk. This will boil out any hardened grease that is plugging the grease fitting. Now just reinstall the zerk and you should be able to get some grease into your part. Now we will look at some other problems that can come up when greasing a zerk fitting.
Can a grease gun be attached to a needle?
Most needle attachments come with a plastic sheathe, so leave that on until the zerk is attached to the grease gun. A grease gun – We suggest a hand powered grease gun that will put less pressure on the seal of the ball joint and allow you to monitor how much grease is getting in the joint.
Can a Zerk needle be used to grease ball joints?
You can use a grease zerk needle attachment to get past the dust boot and pump some grease into that ball joint.
