Front and Rear Limited Slip Install
I am adding Front and Rear Limited Slips over the next few weeks. The front D44, I want to get the Trac Lock LSD Zilla recommended a while back from Tom's. The rear LSD install is a little different. Question is what else do I order for the front and rear installs?
Front Dana 44 LSD Install:
Additive? http://www.tomsbroncoparts.com/product/ ... ditive-new
Gasket? http://www.tomsbroncoparts.com/product/ ... ord-bronco
Front Tube Seal? http://www.tomsbroncoparts.com/product/ ... o-new-each
Yoke Seal? http://www.tomsbroncoparts.com/product/ ... bronco-new
Spindle Bearing and Seal Kit? http://www.tomsbroncoparts.com/product/ ... bronco-new
Ring and Pinion Bearing Kit? http://www.tomsbroncoparts.com/product/ ... ms-dana-44
The rear LSD install is a little different. Justin and Gregg gave me a business card to an older guy in Evergreen that has been rebuilding Ford diffs for like 50 years. I am going to un-install the rear and drop it off for him to remove the spool and add a limited slip then do all the specialized micrometer and big wrench stuff. I am not sure exactly what LSD he is installing but IIRC it is a Motorcraft but could be wrong. When he's done, I will pick it up and install it. Cannot wait to get rid of the rear spool! Viper already has dibs on the rear spool - sorry to disappoint :D. What parts do I need to reinstall the Ford Rear 9"?
Rear 9" LSD Install:
Additive? http://www.tomsbroncoparts.com/product/ ... ditive-new
Gasket? http://www.tomsbroncoparts.com/product/ ... bronco-new
Pinion Seal? http://www.tomsbroncoparts.com/product/ ... bronco-new
Anything Else?
ZOSO looked at the Front Hubs (Warn Premium), axles, steering, etc. looked fine. I noticed Greggs thread on the gear oil to buy. The rear axles are new 31 spline chromoly with new wheel bearings so I think I just need items related to the LSD installs and make it as easy as possible without running to the parts store. I would also like to order everything at once from Tom's if possible. Hopefully ZOSO will let me use the spindle bearing nut tool again :).
Thanks for all of the help so far in this process ZOSO, Viper, Zilla, Justin, and Gregg. Slowly getting my rig snow bash worthy.

Not sure how I missed it, but Wild Horses carries the Track Lock so I will order from Wild Horses instead.

Re: Front and Rear Limited Slip Install
Keep me posted when you get around to doing this. I'd like to put a limited slip in as well.

Re: Front and Rear Limited Slip Install
You don't really need the gaskets. RTV is fine. Tube seals are a good idea while the front diff is out. You don't need the yoke or pinion seal if you aren't changing the gear ratio and it was setup correctly previously. Spindle seal kits may not be needed but you won't know until the front axles are out. They can be found anywhere, part # SK1 I think. Basically just need the new diffs, diff bearings and some RTV. Bearing kits are nice but you'll probably have some parts left over. Rear diff bearings should be bought after you get the diff out. There are several sizes.
I don't remember calling dibs on the spool.

Viper - I know you hated driving my Bronco with the rear spool. I do too, so I am excited to get it outta there for better road manners. Anyway, I think the guy in Evergreen wants the Spool and the 5on4.5 31-Spline Rear Axles that came on my Bronco, toward the work on the 9" Center. Thanks for the great info and part numbers.
Gregg, I will document the install on my build thread for guys doing the same upgrade in the future.

LOL, is that in lieu of the recent snow bashing trip?
Chad - if using RTV I seem to have better results with running my bead on the surface and letting it dry for 10-20 minutes before I install the part. Otherwise it seems too thin and squishes out too easy.

Re: Front and Rear Limited Slip Install
Chad, I would steer away from the ford/factory trac loc limited slip. They are fine for street but pretty much suck off road. You'll want to find one thats a little tighter. Find out exactly what Dan installed as those work awesome on and off road.
And when you order up the parts you might as well order your flairs......

I think this is what Dan did the matching Track Lock in the rear:

Actually, its always been on the list but the snow trip may have moved it up a little.
Keep this thread going!
