Need Some Help With Rough Country Differential Cover

[shaneus]

This will be one of my first posts because i need help from you seasoned guys on what happened. Family went to marble falls offroad park this weekend, had a blast! 3 hours into our 4 hour trek home I went over a Iarge dip i didnt see in the highway. Heard something hit underneath and suspension bottomed out. The rough country differential cover in the front knocked a hole in the oil pan. Yes, its installed exactly per instructions. I searched and couldn't find others that have had this same problem. Yall look at the pictures and see what can be done. I plan on calling Rough Country in the morning. For those wondering, I made the last hour home with no check engine lights, and as soon as I stopped the jeep in the driveway all the oil came out. I know what my thoughts are as I'm an engineer for a living, but wanted to see what your guys opinions are? I wheeled pretty hard saturday with no issues. See pictures.

You made modifications to your vehicle without regard to suspension travel and fitment.

You drove it an hour with a hole in the oil pan.

You need a new oil pan and a (better) lift kit with proper bump stops.

I'm not sure exactly what you're expecting to get out of this thread other than "oh man that sucks Rough Country totally owes you an engine."

Not sure how this happened. You do still have both bump stops? Are you lifted but no adjustable trackbar to recenter axle?
I just can't imagine they have a skid plate that badly designed that it would interfere with the oil pan.

To be fair, I only see their stuff on mall crawlers in my area. Not exactly known for quality either so i'm not surprised if there wasn't actually any meaningful R&D done on most of their products.

I have what I think is a good quality AEV lift kit,

Actually, good point, let me look. Bump stops are there and tight. I have an adjustable rock krawler trackbar. With exact spacing on each side when sitting.

Well for one I was wanting to see if anyone else had the same issue since there wasn't any posts on it, and what could have caused it, a misalignment or something. Don't comment if you don't have anything to add

If oil was coming out when you stopped you might be fine

I would pull the coils and jack up the front axle and see how the contact was made. I might have missed it but what suspension do you have and did you articulate the suspension fully when you installed it without coils in place to see if you would make contact anywhere? anyway that is the first thing I would do.

I have an 3" AEV lift with heavy duty springs

couple of things I looked at the install instructions and it does say to make sure you have clearance everywhere...that does include cycling your suspension. I know most don't but everyone should....also under under your user name it shows you have a 22 willys is that correct?

Yes, 22 willys with the diesel. I pulled up on a culvert both ways to check clearance. Nothing hit. That is kind of why I'm perplexed as to what happened.

I'd pull the coils and cycle everything like @jadmt said. Might need more bump at full compression.

a culvert is not cycling your suspension. you need to pull the coils. do you have a M186 or M210 axle?

 

[RudeJeepin]

Checking on the culvert was, left tire up right tire down, right tire up left tire down. That would keep the center of the axle more or less at ride height or slightly higher.
You also need to do both right and left tire up at the same time. Then the center of the axle will also go all the way up. That is what you did when you hit the dip at high speeds.
The diesel needs more/longer bump stops than the same setup on a gasser. Not all lift companies differentiate between gas and diesel lifts.

I have the M210
