Anyone out there running TF's D44 housing in front? Wondering how they're holding up so far.

I have one, havent had any problems with it. Although i havent wheeled with it yet, i can say that it is beefy. A shop installed mine because it was already there for other reasons. But I dont see installing it be difficult at all.

Because they use the same shitty unit bearing hubs as the factory axle. Most people don't think about getting them in an added width s you can run bigger wider tires without spacers. At minimum if running 37x12.5" tires you should be looking at a 68.5" wms axle with a 4.5" bs wheel. Factory width axles with a 3" bs wheel. A stronger lock out hub will also allow you to disconnect the front driveline for better fuel economy and would allow you to drive should something break up front. You can add the spyntec hubs to the pro rock or the rubicon axle but once you add that to a completely built pro rock 44 you will be at what a d60 will cost.

At minimum I would look at the hybrid 44/60 if I were going to do a 44 up front.

x2 on those reasons, I'd really like a Hybrid under the front of mine. I really would like a wider axle up there more than anything else. Lockouts are just icing on the cake.

I'm staying with D44 because I want to keep weight down. I have Spyntecs so I have the manual hub issue covered. I'm sure they're not as robust as Dynatracs 60 stuff, but they do ditch the unit bearings. The Spyntecs required chromolys and CTMs, so we're in good shape for the time being axle shaft & u-joint wise. If this works I'll swap in slugs in place of the Warn hubs for serious trails. First step will be to swap everything (diff assy, shafts, Reids, Spyntecs) over to the new housing and dial in the caster/pinion angle. Phase two will be as needed, RCVs and if the stock locker takes a dump, starting the swapover to ARBs.

I like mine. I went with the R44 housing. The install was about 15 hours, but it was very straight forward. I did everything except the gears, which I had a guy at Adrenaline Offroad do. I agree with what dirtman and goody are saying, but if you can get a good price you can't beat it for an overall stronger housing.

I have run a TeraFlex HD44 in my JK throughout this year. I have the standard .250 wall 3.25" diameter housing. My axle is 3.5" wider per side for a total width increase of 7" I raced the KOH EMC Challenge, full week of beating it up in Moab for Easter Jeep Safari, and raced a full season of Lucas Regional Short Course. I have swapped the ring and pinion 3 times trying to find the best gear ratio for me. My housing is still in perfect condition, no bending, and the original inner axle shaft seals are still good with no leaking. I am going to put a Spyntec Conversion in the axle in the next month in preparation for the upcoming 2014 EMC Race. I don't think that you can go wrong with this axle. (reasonable tire size and vehicle weight considering). My Jeep was so much faster through the whoops losing the weight of the Dana 60 when I swapped to the Tera HD 44. Just throw in some TeraFlex or Poly HD Ball Joints, RCV Shafts, Sierra Gears and your choice of locker and let it rip!

Thanks, THAT is what I needed to hear! Housing is ordered and I hope on its way from Teraflex. Wish I could do the install myself but I'm recovering from rotator cuff surgery and can't swing any heavy wrenches until March at the earliest. Will farm it out to a local shop.
