Different question about shifting from 2WD to 4WD

I would guess that your linkage is slightly out of adjustment. There is a rod with a lock nut/bolt on it that sets it on the older ones.

I am not sure if they changed it on the TJ, but for the older ones, you are supposed to put it in 4 low and use a 1/8" shim or drill bit between the shifter and it's end gate to have it adjusted right.

I would guess yours is more like 1/4" gap or something like that...

It may be shifting out of 4wd anyway. It doesn't always make an audible "click." when it shifts out, although it may delay shifting out for a few seconds depending on the torque load in the T case. Tapping the thottle will increase the torque load and do the opposite of what you want. If you have an automatic, try shifting the tranny into neutral when shifting the tcase; manual, let up on the gas or disengage the clutch.

All this is valid assuming what you are describing isn't actually being stuck in 4 Lo.

Matt,

Good info. I'll give that a shot when I finally do give 4WD a try. Thanks.

The poor gas mileage and performance loss indicates strongly it is not coming out of 4WD.

I think there might be some other issues re: your mileage and performance losses. Running in 4wd will give you somewhat less mileage & perfromance but not a substantial loss...TJ's don't have front hub locks, so the front axle and driveshaft are always spinning, even in 2wd. If you were in 4wd, you'd feel the "bucking bronco" effect on sharp turns since the front and rear axles are locked together.

If it's actually in 4wd, there won't be ANY doubt. Just get in a parking lot and turn the wheel to full lock. If you're in 4wd, it'll kick and buck. If it doesn't, you're not.

Also, when you shift out of 4wd, do it this way...
