How's the grease getting out?!

Post by IDG » Fri Jun 24, 2016 1:32 pm

Following a semi-paced drive got clunk, clunk, clunk underload.

Stop, looked, lots of grease on spring and surrounding area - grrr

Wheel off...but the boot is dry. We will have a better look but where can the grease be coming from?!

It is vented (circa 1mm dia hole), but surely that's not enough to lose loads of it?

Not funny when it costs nearly £150 for the sexy grease!

Hoping it's like before and not the CV too.

Thoughts appreciated.

You absolutely 100% sure that there's not a hole in the boot. Last time mine had ballooned and split on one of the ribs.

I am not sure (happened to me before too)...but you'd expect to see reasonable evidence on the boot of it coming out but it was 'dry'.

Was a split in the boot.

Is the CV alright and can it be sorted for Thurs though??

Has anyone ever tried some sort of rubber softening fluid on the boots? You know the stuff you can buy for your tyres to soften them. Spliting boots sound like the rubber is too hard for what it is doing...

Does that lower the melting point though?

The boots simply aren't designed for the angles that they constantly run at.

Same can be said for the joints

I guess there's a potential myriad of reasons why my driver-side outer is making a habit of going though, verses more powerful variants of the same thing. :(

I think the effectiveness of a softner will depend on the composition of the "rubber" that the boot is made from - and that is maybe the key point.

Due to the angle they run at the bellows are rubbing together like the FWD car is steering all the time so you need to limit that when you install - Gav is on the money that a softer more compliant boot is probably better but you dont want it eating itself when it revolving.

Also be sure its not just touching the subrame at any point
