2014 P4X, MT, 100k miles looking to install ARB front locker on stock setup. Looking ahead to 150-200k miles, what's worth replacing with things taken apart? Yes, I hear you: might as well Titan Swap m205 for all the reasons, but instead I would like to hear about the preventative replacements and inspections of parts on stock transmission. Pinon? Seals? Etc. Want to have a full parts list for the job. Thanks.
