You do not lube them they are full of grease.if boot tears and splatters the grease out then you replace boot or anymore just as cheap to replace axle. Some lube centers try and sell a lube service on these where they poke a hole in your boot and pump grease in them.This is a no no as it causes your joint to start leaking

What is a cv shaft


Dear Dianne,
Under the front hood of your Honda is a motor or it is also called an engine.
The engine is hooked or fastened to a large container called a transmission, which is also under the front hood.
In order to get the car to move, there are 2 steel drive shafts going from the transmission to the front wheels.
These drive shafts are about one to 2 feet long, and each one drives a front wheel. That is why there are 2.
These steel drive shafts have a large joint at each end of them, so you see why there are 4 joints.
The joints attach to the wheel on one end and the transmission on the other end.
These 2 steel drive shafts are called cv shafts because they have a CV joint at each end, and these CV joints are a part of the shaft assembly.
The CV shafts "transfer" the movement of the engine to the wheels.

Where is toyota constant velocity u-joint located


Like all front-drive cars using CV joints, there are 4 CV joints on the car near the engine. The vehicle has 2 axles (left and right, driving the corresponding front wheel). Each axle has 2 joints, one on each end. Typically the outer CV joints fail first, as their range of movement is greater due to steering the vehicle.

In modern practice the entire left or right axle is replaced when a CV joint goes bad.

Constant Velocity joints and U-joints perform a similar function, but are not really the same thing. U-joints are more typically used on rear-drive or truck-based 4WD vehicles.

When turning the front end makes a rubbing or vibration noise.


This is caused by incorrect & uneven front tire inflation OR a worn out CV joint( constant velocity joint) & this joint is the power transmitting shaft from the transmission to the tires. If it needs to be changed, you'll need to remove the lower ball joint & rim & tire & holddown nut to the CV joint. Hope this helps! Good luck!

On left turns there's a clicking or rubbing sound coming from left front wheel?


Without seeing and hearing the noise in person I can only speculate as to the actual cause of the problem. The issue is more than likely caused by one of the two following failures: 1. A failed CV axle boot on the drivers side nearest the wheel. 2. (less likely) A failing drivers side hub bearing. To me, however, your complaint describes to a "T" a bad CV axle. CV stands for constant velocity. This type of drive axle was designed for front wheel drive applications in order to allow the axles driving the front wheels to not only adapt to uneven road surfaces but also pivot with the steering knuckles to steer the vehicle while maintaining rotational speed. To achieve this CV axles use special joints at either end called trunions. These joints are lubricated with a thick grease which is contained by rubber boots. In your case the boot closest to the driver's front wheel has torn open allowing the grease to be thrown from the joint during driving. This joint, now unlubricated, has dried out and collected debris from the road. Making otherwise silent operation a disturbing load affair, especially when it is put under maximum stress ie a left hand turn.

2002 ford f250 v10 when making turns in four wheel drive the front end starts poping as you turn. you can feel it in the steering wheel and hear it.


Four wheel drive is designed to drive on grave or mud. You will always have a feeling within the steering wheel and the truck will feel as though it is hopping , this is normal on dry pavement. How ever you shouldn't hear noise this is an indication that your universal joint on your front differential shaft is worn. You should have both changed if you are considering driving it in four wheel drive a lot in the conditions that the vehicle was designed to drive in, slippery, muddy,ect.

Sound when turning


Check for worn or damaged CV ( constant velocity ) joints at the ends of both front axles covered with rubber boots. Usually noisy due to loss of lubricant

When i turn my wheel to the right there is a clicking sound and when i hit the brakes the front end wobbles


Clicking noises are usually traced to the Constant Velocity joints (CV joints). Look at the rubber boots, one on each side. If the rubber boots are worn or have holes, you are heading for CV trouble. Sometimes just replacing the boots and re-lubricating the CV joints solves the problem. If the joins are worn, you could be looking at $500 or so each to replace.
