Re: Transfer Case question / 2000 Jeep Grand Cherokee
Lon, I could be wrong on the JGC's t-case as I really thought it was a
chain driven t-case as is used in most Jeeps. Maybe the Quadratrac or Quadradrive t-cases have a clutch but I thought they used a differential to provide for their full-time abilities.

Qtrac version has a form of clutches in it to act like a LSD across center diff. The original Qtrac from 73 to 79 (and I still have one) used tapered friction cones in and tapered hub preloaded to act as a LSD and it too required a specail lube or additive to work properly. (actually the specail lube then was 20 weight non detergent oil with a additive) If you use wrong lube it could act funny and make strange noises especailly in turns. ----------------- TheSnoMan.com |

Re: Transfer Case question / 2000 Jeep Grand Cherokee
I can see no "clutch" in the NP231 [2H 4H 4L N], there is a clutch shaft in the NP242 which appears to be part of the internal differential for the 4H full time [2H, 4H part time, 4H full time, 4Lo] the NP249 has a clutch sleeve [4H, 4L] with the viscous coupler and is somewhat fussy about fluid. Was surprised to see them mentioned as you are correct they are chain driven. All models have have the same diagnosis of noisy, not enough fluid or the wrong one.
