C V Joint Fitting Advise One of the most common causes of a damaged constant velocity joint (C V) is a damaged or torn C V boot, so we recommend that when fitting a new C V Joint onto your driveshaft always fit a new C V boot this should be repacked with C V grease and clipped. Periodically we recommend that a visual inspection be done to check that there is no sign of grease leakage, torn, cracked or damage to the C V boot. We also recommend that on/or around 38, 000 miles the C V joint should be regreased, as around this time the C V grease starts to break down. This involves the C V joint to be stripped cleaned, packed with new MoS2 grease, rebooted and reclipped. This should be undertaken by trained personnel, who will have the correct tools to do so. Driveshaft Fitting Advise First check that the new driveshaft is the correct and the same compressed length as the old unit. Fit the inner C V joint first into the gearbox/differential, once the splines have engaged the driveshaft must not be allowed to fall on its own weight, as this could cause the inner C V joint to be "pulled" apart. The Driveshaft should be straight at all times; you may need another persons help at this point. Then fit the Outer C V joint thought the wheel hub and fit and tighten the hub nut. Make sure that C V boots are protected from any impacts during fitting the driveshaft, as any small tears will cause loss of grease. Checking the Power Steering Fluid When checking the power steering fluid level the engine should NOT be running. Unscrew the cap of the power steering reservoir, the cap normally has a dipstick attached. Most dipsticks will have a hot or cold marking on them, make sure that you are reading the correct mark, as the fluid level will rise when the system warms up. If required add fluid to the correct level on the dipstick. In most power steering systems Automatic transmission fluid (ATF) is used, HOWEVER, some power steering systems use special types of fluid, ALWAYS refer to the manufactures service for the correct power steering fluid for your system. Do NOT over fill the system as this could cause fluid to spray out over the reservoir onto the engine and any other components. Power Steering Leaks Common problem with power steering systems is fluid leaks, as power steering systems run in excess of 1,000 p.s.i. leaks often occur. To check for leaks, wipe fluid away with a clean rag, then have someone else start and idle the engine and turn the steering wheel from left to right. This will pressurise the full system and any leaks will show. Once you have identified the leaking component replace or repair the part. Bleeding the Power Steering System Any time you replace any parts such as the steering rack, power steering pump, or power steering hoses in the power steering system it is important to bleed the system to ensure all the air is out of the system. Should any air be present in any power steering components a “buzzing” noise could occur, the sound normally happens from steering lock to lock. To bleed any air, start the engine and turn steering wheel from side to side to force to air out and keep checking the fluid level and add fluid as necessary.
