Here are the installed pics of my new diff guard. It comes pre-painted black with hardware. $69 at http://www.fourxdoctor.com and based on "ping" tests, the main ring is tube, the center supports are solid
Yes they make one for the D30. You can not protect the entire diff on most stock rigs becuase the tierod gets in the way. A lot of people reinforce the "hump" portion with thick plate welded to the cover, but it is ugly.
Don't think it is really neccessary on any rear diff since you are ususally moving forward.
Definately a good investment. If you loko close at the first 2 pics, you can see a dent in the cover just above the main bar and inline with the left support (small rust colored area). It is about 1/4" from the ring gear from what I measured. If I hit the rock any harder, I might be ordering a new gear set...
I don't know the rear cover may be good too!! Jason, don't you remember getting stuck on the rocks at Hollister below the campground. You had a rock trying to eat your front and rear diff at the same time. As well as one eating your drive shaft too. I think everyone must have blanked that very interesting trip out after torch's evening show. :burning:
You get stuck and have to back up your rear end is prone to rocks too.

I seen and repaired ripped open rear diff covers on the Rubicon. Granted, they may not see as many whacks, but they do get damaged. Heck, had to pound my jeeps rear cover out a few times. Fortunatly, it's never really leaked .. a lot.
Ron can also fab up a diff guard for the rear Chrysler 9.25, but the only problem is that the diff cover has a rolled lip, so you would need to ground that down in order to install the rear diff guard. Has anyone seen a diff guard for the rear that protects the front of the diff housing, other than an axle truss???
That rolled lip is serious PITA. Mine is rolled up and when I need to remove my cover I need to pry, beat and other things to get the bottom 3 bolts out....
Next time I am am going to grind the lower roll off.
I have never seen a gaurd that protects the front of the diff (the nose portion) as it is pretty thick cast steel to begin with. I have dropped on, scraped over and run into mine with out problems... yet.
