Lsd to open diff?

[ttthiel]

Hello everyone. As of now on my off-road truck which never sees the road I have the stock lsd with 3.55’s. I’m in need of a true locker and not a fancy or more aggressive limited sleep due to being 2wd in sand. I am having a really hard time finding a locker for my 2010 9.25 inch rear end.(please drop a link of a locker if anyone knows of one!!)I was looking into swapping my lsd to an open diff if possible. From my understanding I know I will need to get a new carrier but what else would I need? With the open diff I could install a lunchbox and it’ll be much cheaper than a locker from the sounds of it and be a true locker! Please help!!!

Never sees the road? Find a competent welder and have it welded up. Some will scoff at that but it’s cheap, effective, and strong when done by someone who knows their stuff.

Was thinking the same thing. My off-road rig (K5 Blazer with 1-ton axles and 40" tires) has ran a welded rear diff for 20 years now. For straight off-road driving I actually prefer a welded diff or spool as it's more predictable and IMO puts less stress on components than a traditional locker that locks and unlocks.

If you decide to go the route of an open carrier with a lunchbox just make sure to evaluate the total cost. Labor to install an open carrier versus full locker should be the same, but might cost a little bit more for a shop to install the lunchbox on top of the carrier setup. Then add in the cost of buying the carrier on top of the lunchbox. Generally the cost savings of a lunchbox locker is you don't have to buy a new carrier or pay to have the gears setup.

Ok dumb question. The lsd has spider gears that you can weld? I thought that was only on open diffs

Good point! I want to save some money but in the end it’s about doing it the right way as well.

No such thing as a dumb question, right? That’s how we all learn. And I’m still learning stuff...

Anyhoo, the half tons use a clutch type LSD with spiders, so yeah, it can be welded.

The 2500 and up used a helical LSD, which I know nothing pro or con about welding those. Not really relevant for your axle, but maybe the source of some questions.

Awesome! I guess it is dumb of me to assume I have an lsd anyway. To check do I jack up the rear and and spin one tire and if the other spins the same way it’s lsd right?

I’m assuming this means I don’t have lsd?

That’s not a reliable test, especially on a high mileage diff with worn clutches. With experience, you can *usually* tell the difference in how a diff responds to rotating the wheels in opposite directions. A standard diff will rotate the wheels opposite with little to no resistance. Clutches or helical designs resist more or less depending on the amount of wear, lube viscosity, and whether the design uses pinion torque to clamp the clutches. I’m not the greatest expert on the half tons, haven’t had one in a long time.

Based on your latest post I see no LSD indication. The surest method is just pull the cover and have a look.

Awesome thanks for the info!

If you had the factory LSD the equipment listing will say Anti-spin diff rear axel.

2010 has lots to chose from ARB, Eaton E locker and more
2011 not so much
