Same! Any reason to think the Yukon LSD in the front would be easier on the D30?

 

Torsen Yukon tru-trac up front on the D30 for me

Any noise/concerns when making tight turns on pavement?

 

Hi, interested here too... what made you consider the Grizzly over the True-Trac?

Grizzly is an auto-locker which will click back in place after a corner, is it a superior locking device? I'm thinking it may be a better choice for the rear if it does more completely lock, however I've yet to hear anything bad about True-Trac's and I personally really like the Torsen design.... You need to hit the brakes if you get one tire in the air to resume power to the tire on the ground. Is this not the case on the Grizzly?

 

Yes the Grizzly Locker is an auto locker that is 100% traction to both tires but has speed sensing to disengage during turns on pavement. I guess the Grizzly locker is an LSD and a locker built into a single unit. Assuming if you have a tire off the ground and one on the ground with a Grizzly locker that both tires will have power applied without doing anything else. The Grizzly locker seems proven and tested during offroad racing.

 

IMO, locking a D30 diff is a poor decision. Smaller, ring and pinion, smaller gear teeth, less splines on the axle is just asking for trouble.

For these reasons, I put the TruTrac in my D30 (& the rear D44). Functions flawlessly in 2WD, 4WD Hi and 4WD low, street or trail.

 

For me a locking D30 should never be an issues. It's more so for muddy conditions than anything else for me.
