It seems that things happen in three's around my house. In the last 12 months I have replaced three rear ends. One in the wifes Durango, my Dodge Ram and another Durango. Also in the last 12 months I have replaced the heater core in my truck and the Durango. Now the daughters 94 ZJ needs one. Out comes another dash! I expect it will be about the same as the other two ( a pain in the ***) but if there are any tips that could be passed along I would appreciate it.
