Broke Front Diff...Weak Link

Yes, I was just kidding. WRP produced crankshaft pulleys that probably weren't balanced, were dyno tested under questionable circumstances and really didn't fulfill the purpose that the OEM pulley did.

I don't mean to crap on your idea with my sarcasm. After a number of Titan owners got burned pretty bad by WRP I'm a bit cynical. A stronger front differential is a good idea.

I didn't really follow the pulley threads that much...not a big deal to me. My idea is that if it isn't broke, don't fix it; and the engine runs fine...thus the reason I say away from the extreme performance modification threads (I might get ideas...lol).

The good news is that there are other companies that make replacement u-joints for the Titan. I called down to my local Advanced Autoparts store and they had 3 of the premium u-joints on the shelf. So I spent my evening under my truck and the 4wd is not operational again. Although, I am now a little headshy about doing anything with the truck in 4wd (we just got 4" of snow here in KC yesterday). Sucks.

I like the idea of upgrading.

The only problem I see with upgrading the u-joints, is a u-joint breaking sucks, but only takes 45 min tops to change. If the u-joint doesn't break, then you'd probably twist the driveshaft! That takes weeks to fix, not 45 min.

Yep Looks Like Pulling Backards Did It In, Hope Nissan Engineers See This Video And Redesign With Thicker Dana Axles

I doubt there will be any changes..........remember the
Nissan Titan is close to the end of its life.

I had my front diff replaced just a week ago.

The Service manager at the dealership did a little digging and told me that the part number for the front diff has changed ( I'm not sure when) and as far as he knows they haven't seen any of the new ones back yet. He said that the ring would hit the case and push the axle out and that apparently they've done some modifications to the design so this doesn't happen. Time will tell if this make the problem any better.

Nissan Titan Drivetrain = questionable at best. Good Motor/Tranny, but the rest is junk IMO.

I know, Old thread revival batman. No need for a new thread on a long going issue.

Any update on this? I'm getting there. Other than getting a junkyard unit and rebuilding it, with stock part, ugh.


Mecanical god don't curse me but my 7m supra seem to be more trouble free. (soon to be run on holly water and red coolant)
