Re: Early Bronco axles into a TJ...

Why waste your time? Only thing you gain is lock out hubs in the front and a slightly stonger rear with a lower pinion.

I swapped a dana 44 into the front of a tj and it was a stupid idea. It's just not worth it. Std rotation d44 ring gear isn't much stonger then rr dana 30 ring gear. Your tj allready has 297 u-joints which are the most common broken thing anyways. How many unit bearings do you hear about people stipping out or breaking to the point they don't have 4 wheel drive compared to blown up lock outs, buy a set of life time unit bearings and replace em once a year.

For the rear get an 8.8 if your going to go through all the trouble. They allready have the big shafts and disc brakes for a whole lot less then it will cost to upgrade your 9". They are c-clip axles but the caliper will keep a wheel on if you pop a shaft. Higher pinion, more splines, flange style yoke.

If you have a factory dana 44 keep it and slap discs on it.

I'm guessing your tj's axles are in no where near the shape of 1974 alxes, plan on all new bearings, seals, ball joints, steering parts, brakes, ect.

It's just not worth it in a tj to deal with swapping everything in for a little gain you get, an 8.8 rear swap and regearing your dana 30 is a much more simple and just about as strong of a swap. If your poping your dana 30 on a regular basis look into 1 ton axles.
