Yesterday, I rebooted the passenger axle’s inner cv boot on a 2008 Camry V6. The inboard CV joint sits very close to an exhaust pipe so the joint sees high temperatures on a regular basis. When the old boot was removed, the grease inside the joint had the consistency of a XW-20 engine oil. The new grease from the Toyota CV Boot Kit had the consistency that you would expect for CV Boot grease. Is there any way to prevent viscosity breakdown in this application? As you may see in the pictures below, there is a small amount of wear on the rollers (bearings), which I attribute to the grease “failure.” Old grease with the consistency of lightweight motor oil: Prior to re-booting: old boot that was seeping grease. Evidence of grease seepage from the cv boot. The grease was slinging onto the engine timing cover and the p/s pump. You can see the wear on the inner cv joint’s rollers (bearings) from this picture. The surfaces were still smooth though. Had to use a 3-jaw puller to separate the slider from the shaft.
