Question busting up grease on drivetrain ? suggestions ?

I'm seeking helpful advice on how to bust up grease on the underside of the jeeps so i can pull drive line components with less mess.

both trans and transfer case (on both jeeps) have a good amount of caked on grease from years of neglect.

whats the best way to get it all off to avoid getting myself covered from head to toe in grease when i go to pull them.


i'm skeptical on degreasers, cuz the grease is pretty thick......i had my dads pressure washer, a while back, but all that did was push the grease around (it was a cheap pressure washer though, maybe i need a better higher pressure washer?)


maybe i'll load it up on the trailer and take it to one of those DIY car wash stations......that way i wont have to worry about grease on my driveway


Share idea if you got em!

When I degreased my tranny/xfer case (they were out for an engine swap) I found that elbo grease worked best. A scraper, wire brush, screw driver was used to get the thick stuff off. After that I used Gunk (I think that's the brand) engine degreaser with the orange peel in it and a pressure washer to get the final stuff off. I tried a couple of different products and that worked the best for me.

I also did this to get the grease off the bottom of the tub. Then it started to rust!

What has worked best for me is Gunk. They have a product you mix with kerosene or diesel fule at 10:1 or something like that. I have an air powered spray gun that I use to spray it on. Then I let it sit for several hours before tackling it with the pressure washer.

That will get off everything that the pressure washer can get to. After that it takes elbow grease.

EVERYTHING's easy for the guy who doesn't have to do it.

This stuff is hungry for grease. Spray it on, let it soak awhile, then jet spray it off. It might take a couple of times, but it'll come off clean

If it's thick get several sized scrapers and a turkey pan to help catch it when scraped off. Get a gallon of Simple Green and use it with various brushes etc. I soaked 25 yr old rocker arms coated it thick grease it a pan for a few days and they came out looking better than new. Simple Green worked for me and it's safe for the environment.

Your going to be coated in grease and grime if you clean it any other way besides a pressure washer. It can't be helped. If it's thick scraping off some before washing will help alot. The good news is if it's thick it usually will come off in chunks/sheets.

i'll try the de-greaser from the diy carway first.....and then i'll try the products mentioned above.....i think i have an old sprayer i could use for the "Gunk" brand stuff.

i hope your car washed arent like the ones around me, they are really picky about cleaning stuff like that.

I feel your pain.....

This may sound outrageous, but, try this......

Drain the oil out of the engine and brake fluid out of the MC.
Then put the jeep on it's side...you can use an engine lift or a come-along attached to the roof of you garage....or about 4 guys (and 20 beers).....lift it up gently and lay it on the side.

Now it's easy to scrape and brush. If you do this outside then it's even easier to wash off. If you don't have a power washer, then tap into your welder fund and get one...besides the shop vac, it's one of the best tools I have.

After scraping, you can do a series of cycles of Simple Green, power spray, repeat.

all the ones i've seen are unattended...unless theres a guy watching from elsewhere *shrug* these car washes are the automated sprayers....just drive into the bay, and do your thing and then leave.



Jeepdawg....

not to poo-poo your fabulous idea....but theres no way in heck i'm tipping either of my jeeps on their sides on purpose.

Greg, it's a lot easier than you think....

Ok...so make a ramp that will lift it to about 35 deg....then clean it....
