Maverick Tremor offroading limits found again -- broke rear drive shaft

[SouthbayTremor]

Took the tremor out to king of the hammers this past weekend. It handled great. Crawled all the way up the spectators area at chocolate thunder. Lots of comments and people impressed with the maverick. The little tremor actually doesn’t do half bad on small whoops and higher speeds on trails. Just careful with the underbody.

On the last night I was going about 40 mph on a a trail and hit a rock right on the rear drive shaft. Drive shaft broke right where it connects to the RDU. Found out something pretty cool. You can completely lose your rear end and drive home fine. I was worried about it being awd the ptu not liking not having a rear driveshaft but it didn’t mind just a clunky noise below 20. Also I can hear exactly when it engages and disengages which is kinda cool. The rear driveshaft shaft is always engaged from 0-17 mph when accelerating and when your slowing down the rear driveshaft engages when you pass 13 mph.

So I had a lot of fun this weekend. Unfortunately I can’t help but to drive this thing like a side by side. So I’ll keep testing so you guys don’t have to. Truck getting fixed now. Picking up my go fast camper in a couple weeks!

Damage list to date:
2 tie rods
1 cv axle
1 stearing rack and pinion
1 rear drive shaft

A nice set of portal axles would be cool!

no videos? looks pretty cool.

This thought has more than crossed my mind and is not completely out of the realm of possibilities for this little mav.

Though I'd be a bit hesitant to label it as "offroading limits found", if the damage was caused by external forces and not something that broke due to overloading of the drivetrain or driver abuse. This would probably happen to just about any vehicle if it took a direct hit to its driveshaft at 40mph with a rock.

Its not off-roading if you don't break something!

I love seeing a Tremor do Tremor things. Hell yeah!

Looks like you had a good time. Is your Tremor lifted and do you have taller tires?

Yes it is it has a 2” lift from rough country (very shitty lift but the tremor shocks are not half bad so I’m running the tremor shocks with the lift until they go bad then I’ll upgrade to gr40 suspension) and tires I have I believe 245/70r17 in the Toyo At3s.

What ever you guys wanna call it is fine with me. I have two incidents where I broke stuff on the tremor and both have been from hard impacts while not on the pavement. So the drivetrain is definitely beefier than I thought but she’s definitely not a raptor lol.

The Tremors a mini pickup that was raised an Inch. Or was it two, more or less?
It’s not a jeep CJ
Get some shielding under that thing before you destroy it dude !
Maverick abuse, should be a felony
:’P
I got some kind of fiber boards under mine. They look as strong as cardboard.

Jrc full body skid plate coming soon

TLDR, the way most transverse AWD systems work now is it’s always a FWD car but the rear diff clutches engage when you’re accelerating and when it senses front wheels slipping.
Think of it like a 4th truck but backwards and the pcm deciding when to actuate the extra drive wheels.

so this is how I imagined it worked except for one thing is that the rear differential isn’t always engaged which prior to this incident I thought it was always engaged but the rdu would selectively engage and disengage via the cluches but I think the reality is that the whole drive shaft engages when power is needed to the rear wheels and the RDU act more like a traditional differential than we think just with the added clutch packs in order to modulate the amount of wheel spin going to each side. So my point is I don’t think the rear end has the ability to disengage via rear end cluctches I think the rear end disengaged via the cluctch in the PTU and the clutches in the rear do more of an assist to lock the rear rather than to engage the rear. Not sure if what I said makes sense but I do have to say one of the added benefits of abusing your stuff is you get to know it well lol

Unfortunately no, the transfer case is a solid gear and pinion/bevel linkage, there are no clutch packs or a center differential in it. The rear driveshaft is rotating 100% of the time and in the tremor’s case, the clutch packs on either side of the diff before the axles are where all of the engagement and disengagement happen and allow the necessary amount of slip to allow it to be “All-wheel drive” and keep it from being a locked and binding 4WD system.
When you hit that diff lock button, you are effectively locking both rear wheels together but you’re also locking the drivetrain into solid 4 wheel drive with the front and rear axles spinning at the same speed.
Under regular driving, there’s never a fully unlocked condition either, there’s always a very small amount of torque transfer from the system being somewhat viscous.
