As said above, you really should not lock your rear Dana 35c axle. The reason is that its axleshafts aren't strong enough and really with no exaggeration, one of them will
eventually snap while you're on the trail. No matter HOW careful you are, no kidding. And once broken on the trail, it's hard to get the Jeep back to where it can be repaired since the broken axle shaft's wheel will separate from the axle afterwards.
Two options... 1) Lock your front Dana 30 instead. Due to the TJ's axle design, a front locker will NOT affect how it drives on the street in 2wd. Yes I know you've seen advice to only install a locker in the front if you also install manual hubs but that isn't the case with the TJ. You won't even notice its presence in 2wd. It's only when you shift into 4x4 that the front locker would lock up hard enough to be felt. Installed up front, a Powertrax No-Slip locker is silent and undetectable by feel in 2wd. An Aussie or Powertrax Lockright locker up front is undetectable by feel but they can click a little during turns in 2wd... no big deal. Again, it's only when you shift into 4x4 for offroading that they then start acting like a locker but offroad, they're fine.
2) Your second option is to install a Super 35 kit from Superior Axle into your rear Dana 35c. That kit replaces the OE 27 spline axleshafts with hardened 30 spline axleshafts plus it includes a locker, your choice of a Detroit Locker or an air actuated selectable (you can turn it on and off) ARB Air Locker. That makes the Dana 35c strong enough for a locker for up to about the 35" tire size.
Hope this helps.
