I caught a little bit of air last night.. I didn't see a large speed bump until it was too late.. I hit the brakes just before the speed bump to slow down but jumped it anyway. When I landed, my rear wheels were locked up. I dragged the rear end for about 20 feet before I came to a stop. I tapped the brakes to see if it would let loose.. It did and off I went..
Has this happened to anyone else in the past?

Well when you got the back wheels off the ground, you had them locked.......so when it hits the ground its going to drag the back tires, not that hard to understand?

I'm willing to bet he "thought" he took his foot off, but in a panic I'm willing to bet he never lifted his foot off the petal.

What a messy bloody thread!?

I have never had that happen to me before. I'm thinking it had something to do with the rear diffs gears meshing incorrectly. How much air did you get?

I love the, "No I know what he did, I wasn't there, but I know for sure he had his foot on the brake" reply, seriously wtf is that!?

I love even more when people talk out of there you know what without reading......
Did I say "I know for a fact" or did I say I am "willing to bet"? So next time let's use our big brains and read before we post. :bigthumb:

CHARGERTREV: You're a cool guy, I only wish my brain was big enough to understand you even more! While you figure out how to call any of us ignorant/stupid/dumb/smallbrained I'm going to be outside doing something more valuable with my time.

PAC3SRT8 it's one of these situations you can bring in to the dealership and let them take a look at it, as long as you have warrenty it shouldn't be an issue. "This is a matter of fact, I was driving, hit a speed bump, rear wheels locked up, I had to come to a complete stop, and things seemed fine. I'm worried for my well-being, I don't want to be anywhere in the rain/snow and have this happen, and have my car swing around and kill me or others on the highway, please look immediately." Perhaps there's a faulty part or two that isn't yet dead that can be fixed before too late. Good luck dude!

Easy killers! Woo Sa... Woo Sa.. :pray:

I think I jumped a good 8 inches or so off the ground. 1ft tops.. Luckily I had slowed down to about 12mph befrore I hit. So I was dragging the wheels for only 4 or 5 seconds from about 10mph. Why would I have locked up the rear diff?

The teeth between the gears have a tight tolerance mesh and are meant to take a horizontal load. When the rear leaves the ground, whether it was jumping from a speed bump, road surface change (gravel>pavement) or wheel hop, you apply verticle forces on them. The bearings for the gears will allow some give, but that removes the mesh to an unsafe under tolerance and the possibilty of the gears binding climbs.

The diff is a mish mash of crazy gears, all spinning according to the driveshaft, AND the rear wheels, and if you give them a hard enough jolt (such as being hard on the brakes, hitting a bump (which pushes the rear wheels even further to the back of the car - creating even 1-2mm of space between the gears)) it could lock the gears up. However, when you came to a stop, they could have very simply, "clicked" back in to sync with each other. This entire idea could be wrong though. It could have been a simply ABS sensor issue, car saw, "We are moving at 12mph, but rear wheels are not and it glitched.

It could have been your parking brake got set somehow because of the bump, perhaps it's never used and is now faulty.

It could have been the tranny screwing up from a jolt, accidentally slipping in to reverse and back out again.

There's 10 things I can think of immediately, but that's why I also immediately jump to - take it to a dealership and explain it.

Our warrenties here in Canada were 3yr or 60,000km. Most of the '06's if not all were 3 years yah? Hopefully you got yours after Nov 15 2006............. uh yi yi.

The bearings for the gears will allow some give, but that removes the mesh to an unsafe under tolerance and the possibilty of the gears binding climbs.

Just an example - my 2001 Ram had the limited slip clutch system in the diff. A friend borrowed the truck and over spun the rear end, causing the clutch pack to fail. A small chunk of one of the clutch bands broke off - this chunk was THINNER than a piece of paper. That little chunk got stuck between a tooth on the ring gear and every time that tooth meshed with the pinion gear, it over toleranced both gears and after about 50 miles of this (there was no warning it was going to happen), both gears had a big chunk break off and the rear end locked up. That little piece, thinner than a piece of paper was enough to do $1200 worth of damage.

Applying a verticle force on the gears, losing all the mesh tolerance could cause them to lock up. Will it cause damage? Possibly. If it happens a lot, definately.

Yah I'm with you on that. Did you start driving any differently?

They took mine away from me at I think 42k instead of 60,000km like it was supposed to be. Accused me of "Abusing" the car. It broke, when I gave it gas, I didn't know I wasn't allowed to give it gas. Wasn't drifting, or... rallying. Chrysler said, "Sorry we went an axle-specialist to check it out" ..................... axel............ specialist? mmhmm.

Anyway, lets just hope it doesn't happen again for both your car and your own sake haha! Stop jumpin off speed bumps :p

I've messed up the differential in my exploder at 230k miles, and it was real fun. (My old exploder) Just locked up and cost 900 to fix (from my buddy's hillbilly father, not a shop)

Did the abs light illuminate while in air. If for a minute your rear wheels were still under throttle while leaving the ground then they were accelerating faster then the front wheels which causes an abs event. Abs will apply brakes to the rear wheels until the meet the speed of the front again. doing what you did probably caused more of a fail safe mode since your applying the brakes again reset it. I'm on the thought that the rear wheels were locked by the hcu doing its job to reduce their speed and because the situation you put it in is not really something thats programmed into the abs system, it probably just stuck until everything was normal again.
I'd say if the abs light is off your ok. Had you had a rear diff issue, or stuck dump valve in the hcu your abs light would be on right now. The drivetrain, electronics, are all monitored. The only other issue would be tires that arent monitored. Even a internal breakage in the transmission would light the cel and probably abs lights. And any hard break wouldnt have gone away 10 minutes later
