Re: CV Grease flinging out
Mine did this on the driver's side. Not sure if another calmo will do, but worth a shot. If the boot has a seat ring on the end, a tight clamp should keep it from happening. Otherwise you have a small tear you can't see.
Probably need to check mine.
Re: CV Grease flinging out
Can you grab the boot and move it on the axle shaft or the joint housing at all ? Maybe 2 pairs of axles ago I got a set where both outers had the boot just loose enough to slide on the axle shaft. That time around the axles had the pincher type clamps so I took a pair of bridge clamp pliers and crimped them just a touch more.
Re: CV Grease flinging out
I read some information from a person who used to endurance race Neons and they constantly had this type of issue, especially at higher speeds.
It ended up being the type of grease being used and how much was being used. The stuff that was in there wasn't up to the higher temps and they were putting too much in...so when it expanded it squirted out everywhere. For those of us that do autocross, road courses, etc. this might be something to add to the "prep list"...re-packing the CV joints with the correct grease.
Re: CV Grease flinging out
It's been a constant problem with my car since exceeding 120mph.

I was kinda leaning towards this, I will look into changing out the grease. Thanks for the reply

Doh! I'm nowhere near 120 but the constant WOT acceleration and hard braking generates some heat I'm sure
Re: CV Grease flinging out
humm I wonder
if while you had the c-v joints apart and the grease cleaned off everything maybe a little rubber cement on the shafts , the grouve in the joint housing and the mateing parts of the boots would solve the leakage past the clamps?
rubber cement tends to stick pretty good if the surfaces are clean and you let it set on both parts like you're supposed to

I don't see what serious work they are having to do going straight line that creates heat, unless you have some wacky angles.
I have always suffered from physical damage or failures of the boot. Been through at least 10 the last 10 years. Never actually replaced a boot.
Would be interested on preferred low expansion grease.
Re: CV Grease flinging out
I didn't mention it because I thought it was kind of a common knowledge thing, but I've also seen zip ties used on the boots on the "low" parts of the bellows to keep them from ballooning out at higher speeds. Dunno if that's an actual issue for us, but thought I'd mention it.

Even Chrysler did that for speed runs. When they were doing speed tests on the PPG pace cars, especially the Daytona prototype. I have a book at home with pictures in it showing the zip ties on the boots to keep them from "blowing up".
