Dana 35 TTB Modification

[Rzwanzig]

Will a low pinion rear Dana 35 housing bolt to a TTB beam?

No, completely different housing design.

Thanks for the response.

I doubt it.
The ttb is high pinion
The ttb also has the “vertical bolt”
That makes the beam part of the diff strength wise

Good question though you had me looking at my ttb beams yesterday

I’m kinda figuring as much that they will be too different, I still am keeping a lookout for a cheap Dana 35 or preferably a Dana 44 low pinion housing to test on the beams as I have both sets of beams at my disposal. I want to build a rear TTB setup and if a low pinion can be made to work it will strengthen it when used in a rear application, though some modification would need to be made and fabricated to secure the housing in the beam better.

I did some measurement on the beams I have and you can shorten the dana 44 beam on the pivot end ~2.4” each and use a dana 35 intermediate shaft giving you a 60” WMS which would better center the TTB diff when used in the rear.

I’ll post my discoveries if I can locate a Dana 44 low pinion housing for cheapish.

I have my desired drivetrain picked out and now trying to see about axle possibilities before I would settle on using the 8.8 solid rear with 5x5.5 lug shafts.

Rear ttb has been done before
Very interesting

Aye, I’ve seen 2 builds on the forums about them and both have gone slightly different ways and I know my idea isn’t anything new but I want to try and design it and design it well for long term durable usage.

I think it’s cool!! I would consider using the d44 or even d50 ttb beams for a rear setup

I’m leaning to a Dana 44 cause that’s what I have parts wise but the Dana 35 with Dana 44 outers is also appealing (I’m putting 44 outers on the front as well for matching lug patterns and strength) and finding a Dana 35 low pinion will be a lot easier, cheaper (and not much strength would be lost) than finding a Dana 44 low pinion here in VA.

What engine trans and t case? I would be a little worried with a Dana 35 rear axle with a big v6 and big tires

Ford 300 (mildly built), NP435/NP205. I’m shooting for a 3,000lb vehicle after it’s all said and done. 55mph top speed cruiser and trail explorer.

Dana 44 or 50 ttb for a rear axle with that straight six, I wouldn’t trust the d35 back there

It would definitely be pushing it’s limits that’s for sure.

Sounds like a cool and interesting build, but how will you end up with a 3000 lb rig if the Ex weighs about 4000 stock? Especially with that 300, it’s no lightweight! No body maybe?

Shortening the frame to about 100” or less and ditching a big chunk of the body and glass and make tube frame canvas wrapped doors….maybe even swap a CJ7 (that I might acquire mid July) body to the shortened frame. 3,000 is the goal and it will be challenging to get as close to that as possible.
