Jeep stuck in 4wd, need advice please
Posted September 30 2008 - 06:57 PM
I usually switch to 4WD low or full time when driving on the beach fishing.
Then on the drive home i saw its still on 4WD when turning (jumped a bit so I took slow wide turns) It did not want to get out off 4WD and I did not want to park it thinking if it would sit parked like that it would be stuck worse.
Finally while stopping at a supermarket to grab some food I ran over a speed bump at the parking lot and that made it shift into 2wd
Seeing that I tested it and the speedbump freed it again.
What You think is wrong with my Jeep and how do I fix it?
Will anything have to be disassambled costing big cash or can it be adjusted on the lift?
Oh and I think the previous owners of the Jeep did not use 4WD at all or very rarely could this be because it wasnt used much?

The answer is to not use "Low."
4wd HI is what most people use, only use "Lo" if you're stuck.
Coming off the sand and on to the pavement, a reluctant transfer case can sometimes be coaxed by shifting into reverse, backing up 10 feet, and then back to forward. (YES, you stop in between!)

What I really want is to know why its happening and how to fix it so that it shifts smoothly.

With those miles I can't complain. But it works for me.

Also tried switching 2DW > 4PT > 4WD HI while moving slow didnt work.
I do not have the owners manual, I was going from what i read online on the Jeep site.
It says you can switch from 2WD to 4WD HI while moving without using neutral. Neutral is for shifting into 4WD LO.
Anyone know why it sticks and how to fix it?

Yup, same here.
When it gets to 2WD I "burp" the throttle F/R a bit and all is good.
Perhaps the linkage couldbe adjusted, more like the mounts have gone soft.
Soft mounts at the tranny & motor will often allow the transfer case to shift position just enough to mess with linkage adjustments. That's why the burping between forward and reverse does the actual shifting. It tightens the "play".
I replaced the rusted linkage & new bushings. It helped. But the tranny mount needs a poly replacement sooner or later.
Shift on the fly in snow? Not now.

And I can't think of many beaches where you'd need to run a small Cherokee in 4wd low. In fact, my Grand Cherokee has the same engine as my small Cherokee had, and is 600 lbs heavier, and I've never had to run that in low range, either.

Mine gets stuck switching from 4HI to 2WD sometimes too so 4LO is not the main problem
Has anyone fixed this problem in their Jeep or just found ways to make it switch? (like driving backwards)

PS; PM returned
Very rough rule of thumb, for me;
When on the beach, and coming to a stop, if I can take my foot off the gas, pop it into neutral, and it rolls to a stop, then 4 Hi is do-able.
If it feels like someone applied the air brakes, then I seriously consider 4 Lo.
It's a good way to determine strain on drivetrain / engine.
Also, if I'm just rolling along very slowly and glassing things I may go 4 Lo just to reduce the speed.
Keep an eye on the "Temp" guage. If you see the temp getting high you can effectivly increase the cooling capacity by turning the heater on high. May not be comfortable but it'll help your engine smile while deciding on a larger radiator or increased air flow.
If you see the temp increase, smart thinking is your tranny is getting hot too. Swap out to a bigger tranny cooler with the radiator may save some grief down the road.
Generally speaking, unless something is seriously wrong, the Cherokees and Wranglers should be very beach capable with modest tire attention.
I know nothing about the newer Grand Cherokees other than looks though. I do see some in the off-road clubs (crawlers), but most folks seem to toss a lot of $'s into them to get them to hang with the Cherris, Waggys, and 'Yotas. in comparison.

I seriously consider airing down more.
