Well some of you may know that I had problems with my front differential in the past. When I had the vehicle in 4 Hi or 4 Lo and turned to the left or right there was a loud clunking/banging coming from the front. So since I am still in high school I had my shop teacher look at it and did in deed say I needed a new front diff. So he referred to a guy that he always goes through and got a nice diff for $100. So we put it in and never really got to test it. So we had our first snow storm here in Wi on Sunday and went to try it and the front diff wouldn't engage so after further research the problem was the washer that goes between the stub shaft in the case and the output shaft that goes to the CV joint. (I hope that makes sense) That being said my instructor and I took the axle tube off and inspected the gears and everything was okay. What happened was the washer slipped between the 2 shafts and wouldn't let the collar fully engage. I got all that put together and went to test it tonight and the same clunking/banging noise when turning...WHAT THE HECK??? So I think it is the front actuator but don't want to spend that kind of money unless I know for sure it is the problem. What else could it be???
Also when I went to put it in the shed tonight and tried to take it out of 4 Hi and my push buttons went black so now my Suburban is stuck in 4 Hi. The front diff, thank heaven is unlocked but not the T-Case. I checked the fuse in by the door but all good.
The Suburban only has 182K and had the T-Case replaced in 2014 (NP246). All this is do because the previous owner used 4 auto a lot.
Please let me know where I can start. Thanks to all in advance! Ben
