morning. i have a 1999 grand cherokee ltd 4x4 with a 4.7 v8 and a quad drive trans. making a left turn it makes a thumping sound. when driving on the road it keeps on thumping. i am thinking that it might be the chain is the problum. is there a way to change the chain without removing the case. thank you, jim.
Good morning, Jim. Based on the symptoms you described, it's possible that the chain in your 4x4's transfer case might be causing the thumping sound during left turns and continuous driving. However, I must advise that changing the chain usually requires removing the transfer case from the vehicle. It's a complex and involved process that requires specific tools and expertise.
If you're not experienced with working on transfer cases, I recommend taking your Jeep Grand Cherokee to a qualified mechanic or a Jeep dealership. They can properly diagnose the issue and perform the necessary repairs to ensure your vehicle is in good working condition. Safety should be the top priority, and it's best to let professionals handle such technical repairs.
I am thinking about buying a 2005 Cherokee Laredo top of the line. I was not aware that there was an awd Jeep. Either 4x4 or rwd. Does the 2005 have a awd? The car I am thinking of buying the seller said it was awd. Just need to know. Thank you.
Hello,
will removing the viscous in my ´97 ZJ (NV249) make the car only run with rear wheel drive in 4HI (which will be a 2WD then) and in 4LO I´d still have 4WD locked with low range?
Thank you and kind regards,
Hendrik
We have a 1998 4x4 Grand Cherokee- No owners manuel ,does the jeep stay in 4x4 all wheel drive all the time? if not , How does it work ? do u need to shift and how and when HELP!!! What is the procedure? what do u leave it in daily driving>? Help!!!
Tell us which modes does the 4wd lever have, or look it up here www.wjjeeps.com
If you Jeep has a setting for 2WD + 4WD part time +4WD full time, then you can use 2WD or 4WDfull any time (slightly better gas mileage and less road noise with 2WD). If yours does not have these positions, then you have full time 4WD, just leave it alone.
Never use 4WD Part time on dry pavement, only slippery surfaces.
ummm it be helpful if we knew which transfer case your 98 zj had and the motor , they came with 3 motors and I believe 2 transfer cases but I'm kinda pretty sure they actually all came full time AWD with a 249 quadra trac (4hi/ neutral /and 4lo ) only time you should be shifting that transfer case is if you get stuck in deep snow at low speeds or in a similar situation in mud or if your offroad going slow. But you must have the transmission in neutral and at a full stop pull the transfer case shifter back to neutral then to 4lo .put the transmission reverse back up 5 feet (not totally necessary but I do it with older jeeps) then put it in drive and go! ...now with all that said you could possibly have what's called a 242 select trac transfer case the way to tell is to see how many selection you have. If it' has full time(awd) /part time(4hi)/neutral/4lo and this one would shift the same way as far as 4lo ...you can shift into full time on the fly (while driving) hope this helps !! BTW THE 249 IS A CRAPPIE TRANSFER CASE 🙄
My 1998 AWD Quarda=Trac,Will not come out of AWD Lock. What should do to correst the problem?
I want to know if all the four wheels in the car turns in 4x4.
will using 225/75r/16 tires on all 4 hinder me. I have 225/70r/16 now,I know the speedo will be off X2 mph
1997 Cherokee,
My daughter called me and said lever is stuck in Part-Time position and wanted to know if will be ok to drive home. She was in the mountains on snowy roads so she put it in PT, so told her to just take it easy and don't go to fast. This Cherokee has 2H PT 4H 4L on the lever. I and not familiar on how this system works so hope it did not screw things up but she needed to get home. I know 4H is ok to use on the road but what is PT for. Of course i will take it in to fix the prob just wondering what uall might have to say.
Thanks rj
The most basic question:
AWD=four tire replacement policy
4x4=does not
How do I know -- FOR SURE -- whether or not a vehicle is a pure 4x4 or an AWD?
Do I have to replace all four tires on either of these vehicles (see subject line)? An AWD requires all the tires to be near exact. However a 4x4 does not (as I understand it). From what I have read, I think the quadra-trac requires all four tires to be exact. And the select-trac would also, if placed in the full-time four wheel drive.
Am I correct? Please help me understand the reason why I am or am not.
I have been unable to locate any site that indicates which vehicles have the four tire replacement policy.
Thank you.
Hi, let's move away from using the "4x4" and "AWD" terms, because noone knows what they mean for sure
The answer for your question is yes, you must use all four tires of the same model and the same wear for both quadra-trac and select-trac systems.
In theory, you can use different tires for select-trac if you know what you are doing and you are not planning on using the four wheel drive mode.
Worn tires? Slightly different tire sizes?
The NVG249 transfer case utilizes a viscous coupling clutch to power the front axle. I would keep the axle speed difference at less than 2% [putting the new tires on the rear]
The NVG242 transfer case has a center differential, 48/52 split. I would keep the axle speed difference at less than 1% (assuming you are actually using four wheel drive, not just the rear drive setting) again putting the new tires on the rear axle.
