Jeep Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name isXXXXX you for allowing me to assist you! I know exactly what this is. The front and rear differentials have clutch discs for the Trac Lok option. When the gear oil gets old and breaks down, it can cause those discs to chatter. Do this: have the gear oil changed in both differentials and add 1 bottle of Mopar limited slip additive to each differential. Then do several figure 8 maneuvers to allow the additive to work itself into the clutch material. This should take care of this problem.
I hope this information helps, and let me know if you need further assistance with this.
Hey Chris. Thanks for this information! I have one more query. Before we bought the Commander, we did a CARFAX among other research. Luckily for us, this car was a trade-in at the same dealer where it was originally purchased so we have all maintenance records to boot. On the CARFAX, it states "Transfer case fluid flushed/changed." on the dealership service dept "Summary History Display" is says:
7/2/2013 30DOZDIF Differential Svc
30DOZDIFR Differential Svc
30DOZTCASE Transfer Case Sr
02DOZ01 SUSPENSION DIAG
Can you translate that for me? Was there work done on the differentials as late as July 2nd........ and if yes, why would the problem recur so quickly?
Well Jack, it does look like the differentials were serviced back in July, but there is a possibility that the additive was not used. It is very important to use that additive.
