Wanted to know if any of you XJ NP229/NP228 owners or users have/had any problems or concerns with this particular designed transfer case crackling in certain places -I am referring to the fact in my opinion that there is an inordinate amount of unsupported transfer case weight,... planetary gears,viscous coupler ,etc..hangeing off the back of the five or six attachment bolt points attaching it to the end of the transmission-I have recently repaired + rebuilt my NP 229 after a few cracks,stress fractures and now have added an additional double-cardan component to my newly balanced driveline but I am still worrying and viewing all this relatively unsupported transfer case + double-cardan driveline weight as being somewhat more problematic in the near term future-I really like all the options with my ole NP 229 transfer case but I am wondering about the wisdom of contiueing to invest/rebuild this unit-Is there any other transfer cases out there that have a better compact/balance weight and that have about the same low four-wheel drive options as the ole NP 229/NP228 transfer cases-
