Select Trac FT 4wd

With the recent weather here in Illinois I have had my first event for using 4wd. I was on the way home last night when road conditions gave me reason to shift into 4wd. I slowed to a safe speed @20mph and shifted from 2wd to FT 4wd. Now I have owned 4wd vehicles in the past and I can feel when it shifts into 4wd but this was different.

When the road is patchy, the front axle seems awfully grabby. If I hit a dry spot or snow free area it feels like the WJ is in 4LO. and I do not feel comfortable driving too fast with it feeling that way. If I get the WJ back on snow/ice the front axle feels smoother but not like I feel comfortable to scoot along at 55mph because I know as soon as I hit a dry spot it will really grab the wheel.

Any ideas on where I go from here? Also, The shifting out of 4wd back into 2wd is like waiting for the second coming of Christ.

Is it necessary to pull the center console to make adjustments if they need to be made?

Thanks in advance.

You shouldn't notice a huge difference with the higher speeds. I drive mine in that mode all the time. However, you may experience some binding when tooling around in parking lots and such because both wheels are under power.

You say it acts like it is in 4 lo. What do you mean by that.?

It should shift out of 4wd if you allow it to coast for a bit. Sometimes I have to do it a couple of times but not more than that. If it takes longer or if that doesn't work you should have it looked at.

If I am going the legal speed limit it just feels grabby as if I am going way too fast to even consider being in 4wd. And forget about having one tire on pavement and one on snow or ice. You definitely get yanked onto the dry pavement. I got pulled over yesterday by a county deputy. He thought I was DUI. Told him I was trying to shift back into 2wd and he wished me good luck..lol

You've got something else going on there. Locked diffs? Do you know if the PO put a locker in there?

Agreed. Something isn't right. I've had mine in full time this week when driving on the wonderful Springfield roads. You can hardly notice it except for the obvious added traction.

Chris this is exactly what I was expecting, just the additional bite. I am pretty sure the PO left it factory, no locker. I have done some searching and I am finding more posts regarding an adjustment on the cable. If I had known I was going under there today I would have washed the WJ. It is a crusted mess in the garage right now from the drive home. UGH.

I'm sure it's nasty under there! It almost sound to me like you're in Part Time... Adjusting the cable would fix this if that's the case.

Sounds like it's not going all the way into fulltime, instead you are really in part time. When was the fluid last changed? Also, it's good practice to shift through the 4wd gears a couple times a month just to keep everything moving. When the shift forks sit for awhile, they tend to stick. I would start with a fluid change and then shift through the gears for a solid 5-10 minutes.

I am going to be replacing the shifter seal on the transfer case. I will at that time be doing a fluid change. When it was done before by PO, no clue, but the fluid is cherry last time I checked the level. I am doing the seal because it has some staining on the case, nothing serious.

I suppose I have to remove the center console to get to the shifter cable adjustment, correct? I will lube the snot out of it when I get in there as well.

Before I take the center console out, can someone confirm that there is an adjustment on the shifter? I don't see anything about adjustment, only R/R on the cable in Haynes. Thanks.

If your tire diameters are even slightly different the 242 will have issues like this. My old tires had not been rotated properly so one pair had a few 32nds less tread. When trying to shift to FT it would sometimes get stuck in PT. It would also stick in PT when shifting to 2WD. My solution was to shift to neutral first then to FT and make sure my tire pressures were equal. When shifting back out of FT I'd go to neutral then swiftly shift it directly to 2WD.

With my new properly rotated tires I haven't had any problems at all.

I haven't had the shifter apart at all.

^This, plus having consistent tire pressure on all 4 corners make a huge impact on shifting into/out of FT and PT.

You could also try to reverse slowly, shift from 4wd to 2wd and then quickly reverse faster. Works for me like a charm - smooth as butter.

Leave the console alone (for now). The adjustment is actually at the cable connection near the transfer case. Look at the attachment to the case and you'll see what I'm referring to.

A bracket should be looked at first for where the cable changes over to the actuator rod and then the rod changes to a ball/socket setup at the TC lever.

Agree that the basics should be checked first as it sounds like there's a Part-time characteristic not letting the wheels slip as intended as they need in Full-time.

I use Full-time throughout the speedo range with no issues and have for years. Mostly I stay in 2wd and am certain to shift through all modes about every oil change.

I think you have a mechanical issue and you're on the right track, but it does sound like you're stuck in PT. The Selec Trac seems a bit prone to this IMO. I have better results when I slam it straight into FT (no hesitation at the PT setting) and then slap the skinny pedal. My Jeep is also more cooperative if its warmed up as opposed to stone cold. Stopping and then reversing as suggested also seems to aid in getting it to drop where its supposed to.

The FT on Selec Trac is awesome! I've been in it for weeks now, great feature.
