   You need to remove the skid plate/crossmember (6 3/4 bolts at the frame and 3 nuts at the trans mount.). Support the trans first with a jack and a block of wood before removing. Remove the rear drive shaft from the differential and pull it out of the transfer case. Unbolt the front shaft from the transfer case only and wire to the side with a coat hanger.Disconnect the vacuum connector from the top and the speedo cable. Unbolt the shifter and bracket (tricky operation). unbolt the transfer case from the trans and pry it rearward with a floor jack under it. Reverse operation to install. The 87 used a different case than the 231 from the factory but the 231 will work. You may have a concern with the length of the shift linkage. If you do anyone with a welder can extend it for you. Good luck hope this helps.

Where can I find information on which transfer case my 1998 Durango 5.2 has, the NV 231 or 242?


look at the transfer case shifter knob, if it has 2h, 4h, 4pt, n, 4l, you have a 242.

I need instructions on replacing the clutch in a '94 Chevy Blazer 4x4, 350 engine. Specifically the pilot bearing, throwout bearing.


The pilot bearing is pressed into the flywheel and you need a pilot bearing/bushing puller. Some A/P stores will rent it to you for free (deposit). the throwout bearing is held onto the clutch fork normally by clips. Sometimes you have to take the "fork" out to get the bearing off.

Make sure to note how "deep' the pilot bearing/bushing is so that when you install the new one it is set at the right depth.

Need diagram to change fluids in transfer case and front and rear diffential for a 2003 dodge ram 3500 4x4


This is pretty straight forward once you have a few basic tools. You will need a suction pump and a bowl/bucket type container to put the old fluids into.

Both the front and rear diffs should have a rubber inspection plug you can remove to pump the old stuff out, and the new gear oil in.
Synthetic fluids last longer and work better.

The transfer case should have two threaded allen plugs (or similar) that are removed to drain and then refill the T case. Remove bottom then top to drain. Reinstall bottom then refill.Then reinstall top.

Service 4WD switch


Need replace it; the switch is on the Transfer Case.

In order to get the correct switch you need to determine what type of transfer case you have. You can do this by crawling under the vehicle near the middle and look for a small round metal tag mounted on the back side of the transfer case. Once you have that number (new process type 231, 242, 249...). If your local jeep dealer is of a friendly sort you may even be able to avoid all the crawling around and just tell the parts manager your VIN# and he will be able to tell you what type transfer case you have - provided that it is the factory installed original.

Hope helps.

Silverado makes weird noise at 70 mph. Mechanic said it's the transfer case and also found a leak therein - wants $400 to take it apart to find the problem or we can just replace. Not sure what to do - pay...


It's probably the chain in the transfer case. I had mine replaced at 150,000 miles and it cost $1500.00 to do a full rebuild. And that included them removing and installing the transfer case and a new yoke for the driveshaft.( Because the play in the transfer case grooved the old one.)

Computer says to check 4WD Switch on 93 Jeep Grand Cherokee.


I just fixed the same problem with my own GC Limited - and it WAS a dealer part (in my case). In order to get the correct switch you need to determine what type of transfer case you have. You can do this by crawling under the vehicle near the middle and look for a small round metal tag mounted on the back side of the transfer case. Once you have that number (new process type 231, 242, 249...) you can order the correct part.

If your local jeep dealer is of a friendly sort you may even be able to avoid all the crawling around and just tell the parts manager your VIN# and he will be able to tell you what type transfer case you have - provided that it is the factory installed original.

According to the mechanic who works on my 93 Jeep it's one of three things:
1) Corrosion on the connector to the switch (which is located on top of the transfer case).
2) A bad switch. Part cost about $22.00, or
3) A bad console display. he says they have had a fair number of console display units fail. That one runs about $240.
My Jeep display it only once in a while. I have checked the connections and they are fine so the switch replacement is next. If that doesn't fix it I will opt to ignore the error.

Hope this helped (remember comment and rated this).

Transfer case removal


Suzuki Samurai/Sidekick/Tracker 1986-1998 Repair Guide
Transfer Case Assembly - REMOVAL & INSTALLATION

Samurai Models
Even the 2WD Samurai uses a transfer case. Rather than use a straight line driveshaft from the transmission to the differential, the Samurai leaves the transfer case in place and replaces its internal working with a simple offset gear mechanism, thus keeping 2 of the 3 driveshafts used in the 4WD vehicle.
  1. On 4WD vehicles, remove the transfer case shift lever.
  2. Raise and support the vehicle safely.
  3. Drain the oil from the transfer case.
  4. Matchmark and remove the driveshafts from the transfer case assembly. Not all of the driveshafts need to be completely removed from the vehicle, just unbolted from the case flanges. In most cases, the shaft or shafts on one side of the transfer case can be repositioned and supported out of the way.
  5. Support the transfer case using a suitable transmission jack.
  6. Disconnect the speedometer cable from the transfer case.
  7. On 4WD vehicles, disconnect the 4WD switch lead wire at the coupler.
  8. Remove the three mounting bolts and/or nuts securing the transfer case to the chassis, as applicable.
  9. Carefully lower the transfer case from the vehicle.
To install:
  1. Position and install the transfer case. Tighten the mounting bolts to 159-248 inch lbs. (18-28 Nm) and/or the mounting nuts to 19-25 ft. lbs. (25-34 Nm).
  2. On 4WD vehicles, connect the 4WD switch lead wire at the coupler.
  3. Connect the speedometer cable to the transfer case.
  4. Properly refill the transfer case with an approved type of gear oil.
  5. Align and install the driveshafts to the transfer case.
  6. On 4WD vehicles, install the transfer case shift lever.
  7. Remove the jackstands and carefully lower the vehicle.
Sidekick, Tracker, Sidekick Sport and X-90 Models
On these models the transfer case is bolted to the transmission and takes the place of the 2WD transmission's extension housing. Therefore, transfer case is removed or installed as part of the transmission assembly.

Hope this help (remember rated this and comment).

Transfer case


On the back of the case you should see a round tag. The numbers you are looking for are right on there.

Cracked rear transfer case housing


There should be a round tag on the rear of the case that gives the model like 231 or 243. Give me this number, and I'll tell you if you can remove it and how.
