Is locking rear diff necessary to do the trails at Leadville Colotado?

I purchased a stock '06 TJ earlier this year and pretty much have it set up for motorhome towing, but am unsure if i need to spend the $ at this time for a locking rear differential. We are planning a trip in early July to Leadville, Colorado and am wondering how much of a risk i run of getting stuck and upsetting DW.... Do i need a locking rear diff (open frt) to run anything at Leadville?
BTW, any advice on with trails to prioritize? We'll be there 3 days.
Thanks.

Little more info on your Jeep would b e helpful.
Axles numbers and gearing. Motor and transmission.
Most say do not lock a Dana 35.

Mosquito pass is definitely worth it. No locker needed there.

Thanks for feedback. More details on TJ: 6 cyl auto. Stock tires (28's??), no lift. Dana 35.
I was planning on installing Truetrac LSD, and if wife approves 31" tires, but need to save chor that one.

you could do an aussie in the front, they run around $200 and are mostly invisible in 2wd but add a lot of traction in 4x4.

That's a good suggestion for your front axle. Never install a locker into a stock Dana 35 axle, its factory axle shafts are not strong enough for a locker which can easily double the load seen by an axle shaft.

I second that! That will take you to highway 9 on the east side of the divide. Go south on highway 9 to Fairplay. Stop in at the Snitching Lady Distillery and order an old fashion--best one I've ever had!!!

Excellent. Thanks for the input.
So no LSD on a Dana 35? Too bad. I was looking forward to that job. So:
A. I don't need rear LSD for Leadville trip
B. I should upgrade axel before adding LSD.
C. Hit Snitching Lady Distillery off Mosqueto trail
Thanks again.

Disagree.. lsd on d35 w up to 31's and SENSIBLE driving should be fine... an lsd is not nearly as hard on shafts as a locker... after that some 1541h shafts will allow a little more tire or more agression... then a super 35 kit ups the ante again for up to 35's and a locker...

That said, a front swaybar disco kit should take you just about anywhere a stock tire'd jeep belongs imho...

Take it easy, don't outdrive your experience level and you'll be fine...

No, we said no locker in a Dana 35. A LSD and locker are two completely different devices, you can install a LSD without problem. With reasonable offroad driving, you can run a stock Dana 35 with a LSD like a Truetrac up to 33" tires. I ran front and rear Truetrac LSDs with 33" tires for several years on some fairly tough trails without problem before swapping both out for lockers.

LSD devices are helpful on the street and on easier trails that aren't so uneven that they lift tires up off the surface. Lockers are for trails uneven enough where a tire is lifted up off the trail surface.

Here are a couple articles I wrote on lockers & LSDs 15 years ago. If you read them you'll know more than the average Jeep owner.

Jerry, thanks for the article... I understand. I can see that a LSD like the Truetrac would be a good compromise for me as my wife has started driving the TJ as her second vehicle, and the ratcheting lunchbox type locker would not go over well at all.

A Powertrax No-Slip lunchbox locker doesn't make the clicking/ratcheting sound other lunchbox lockers like the Aussie and Powertrax Lockrite do. It'd be a good choice for the front axle, it is virtually unnoticeable when driving on the street in 2wd. I had one in my previous TJ for nearly ten years.

X3 on Mosquito, itís on my annual list of trails. Another easy one close by you can do close to stock is Chalk Mountain. Some amazing views. In front of the Jeep is ~1000 ft cliff. For more decent ideas, post up in the Colorado Forum on here when you are in town, some of us will probably join in.

Jerry, thanks for powertrax clue. Why not install on rear diff as well? Much cheaper and easier to install than detroit truetrac LSD.... I can see that it would definitely increase risk of axle shaft fracture. That why?

Keva, we'll definitely add Chalk to our list. Outstanding pic. It was so good DW actually did not say "whatever..."

Yes adding a locker to your stock rear Dana 35 would significantly add to the odds you'll break an axle shaft... which are pretty assured so long as you run the axle shafts the factory installed. Lockers in a stock rear Dana 35 usually result in the axle shaft snapping like happened to a friend of mine in the photo below. We didn't know she had a Dana 35 or we wouldn't have let her go on the trail she was on with us. I heard it snap.

Also, when in the rear, lunchbox lockers are notoriously badly behaved. They pop, bang, lurch, etc. when in the rear axle and on pavement. Lunchbox lockers are fine and well behaved when in the front axle. The reason is the rear axle is passing torque through the differential (locker if present) 100% of the time which makes it hard for a lunchbox/automatic locker to unlock for turns.

The front axle's differential only sees torque when you're in 4Hi or 4Lo and in those conditions, you're on a low-traction surface where the bad behavior is negligible. On the street in 2wd it's a non-issue and a lunchbox locker in the front is a non-issue.

I ran 33's on a lunchbox locked D35 for 15+ years and never broke a shaft. I avoided shock loading when i could and it worked well and i would do it again. But there is always that chance you could break a shaft in the worst possible situation. That's why i finally swapped 44's now i can drive my jeep like i stole it.
