Heavy amount of grease, don't know where it came from
 

I was installing my new brakes and rotors I got from Brake Performance and on the drivers side right on top of the lower control arm was a good amount of heavy thick grease, like someone had take a grease gun and shot a load on top.

I could figure out where it came from. Anyone have any ideas?

First thing I would look for is a hole or tear in the CV boots. If they are torn, they will throw grease all over.

The boots can tear easily around where the clamps are.

Having not dealt with cv boots, are they regreasable or would it need to be replaced. I'll check in the morning but how hard are they to change yourself?

From what I gather, it is easier to purchase a whole new or remanufactured half-shaft.

Mine had leaked a bunch of grease from around the clamp area. I didn't even notice until I installed my lift. I put some caulking on it to seal the tear. I'm sure it is missing a bunch of grease in there somewhere and I didn't attempt to replace any, but I haven't noticed any ill effects. I will just buy a reman half-shaft if I ever have troubles with it.

The problem is, if grease got out, dirt got in. That will destroy the CV joints. Half shafts are not that expensive.

Mine got a tear and I bought a re manned one from o reileys for 60 bucks. They take yours as a core but it was an easy decision as they are still a ford part just re manned. Heck ford here charged 65 for just the boot.

Yeah that was my next question regarding aftermarket or reman. I noticed a new one is around $250 from ford.


I haven't been able to find a guide on how to replace the half shaft specifically for our year truck. Any special tools needed or is it common sense once you get in there?

I can't quite remember how I did mine. I know on the trans side there is just like eight bolts. On the hub side it seems to me like there was just a snap ring and it came out. I know I removed my rotor and that was not necessary as I was just trying to figure it out at that point. But yeah definitely go with an o reileys re manned one. Plus they have a year or lifetime warranty. I can't remember but I haven't needed it so it doesn't matter to me. -brent

Before it reached it's 105 peek today I went out this morning and investigated the boot and all items around it. I found no crack, there was no grease on the boot or any where around the shaft. I pulled back on every rib on the boot and checked top to bottom and couldn't find a thing. I'm perplexed if it's even where the grease may have come from.
