Spray on grease any good?

[richb]

This spray on grease they all use, is it actually any good?
My steering UJ's have been creaking for a while now, however as the car was
in for a service a few weeks ago I thought I'd let the service guys sort it
out. Nothing to worry about was the report and everything has been greased.
A few weeks later and it was creaking again, so I just sprayed a little
3-in-1 all over both UJ's and guess what? It's all lovely and quiet again.
Begs the question whether they spay on grease ever gets to the nub of the
matter or simply makes an impressive white mess all over the place!

The top UJ gets cooked by the exhaust so whatever you put on there is unlikely to last long. The problem with binging more and more grease and oil on it is it attracts dirt and pulls it into the joint, making a nice grinding paste. The best solution I've found is to put a gator over each UJ (the ones I used were the rubber gators for the end of a steering rack). Gives a lot of heat protection and keeps the dirt out. I was getting through the UJs every fifteen thousand miles or so but since this mod it's lasted 60,000 miles and counting.

Spray on grease has a solvent in it to make it spray, and so will dissolve away more grease than it puts on - it's o.k. for pushbike chains, and lightweight applications like that, but not for serious stuff like UJ's.

You could try redline CV2 synthetic grease with a 900F melting point its proximity to the exhaust shouldn't be a problem,I'm using to try and cure a problem I've being having with the grease melting on the outer CV joints and weeping out in the rear uprights.It's not cheap mind so you might want to use the remainder to replace the std CV grease , it's available from demon tweeks.You will also find that the heat in this area kills the rear upper wishbone bush (on both sides) I'm experimenting the a simple heat shield for the bushes though I'm sure it would help the steering U/J to.

Hope this helps

Wurth HS2000 i think its called that, is very good its a spray grease that penetrates, i always thought that U J's with grease nipples were best.
