Bad limited slip? Pics inside, also trutrac questions

[snopro_03]

Ok guys I'm haveing a weird issue. First accelerating while turning I'm getting horrible rear axle chatter. On occasion accelerating heavy from a stop and not turning I get a bad chatter. Basically i'm having a difficult time getting my limited slip to unlock, and when it does i'm getting these noises. YES i've changed oil and have added over 8OZ of motorcraft friction modifier alittle at a time. Driveshaft u-joint's I did this month from a high speed vibrations which is gone now. Tonight it snowed and it was alot worse so I pulled my cover off againnn... The only thing i'm finding out of the ordinary is a gap in between my last few clutch packs shown in the pics. Is this normal? Granted my diff is bad I need a parts list and the best place to buy a detroit trutrac.

I have a POS True Trac in my rig. I'd rather go through that Trac Lock than use another POS True Trac. Left turn, nail it, locks. Right turn, nail it 1 tire fire. 2 foot it, 2 stripes then right side only.

Yeah, I f'in HATE that $600 POS True Trac in my truck.

Oh yeah, you can buy fluid with friction modifier mixed in.

Well your prabably the first person I've come across on here not liking the trutrac. Either way i'm not rebuilding my stocker because I know i'll be doing it again later on.

Thanks for the Input man.

how can you tell if u have a limited slip in your truck

[dfish1247]

Apply brakes, mash throttle, release brakes, and see how many tire marks you have. That's the easiest, I think and don't quote me but all the superduties came with ls, but they suck. I replaced mine with a detriot locker. Works much better for me as my truck stays on the road more than it does off.

Love my Trutrac, money well spent when i rebuilt the rear diff. I dont hot rod my truck on the road, but it does have a lot of off road farm experience and i rarely have to get out and lock in the hubs for 4x4, i get around in 2wd pretty good

I know we've talked about this before, and I am pretty happy with my Tru-Trac. I can't say that I have ever experienced what you are describing but that is just my personal experience.
Chad, I wouldn't rebuilt the stocker if I was you. I don't think they handle additional power all that well, especially if you want to upgrade turbos or injectors later. I know you can buy a Tru-Trac on line at 4wheelparts.com and a bunch of other places. If you want to buy from and actual person, Performance Diesel in Green Bay is a detroit distributor. They could help you out with a parts list and some tips on the install.

Maybe I got the only bad Truetrac ever made, IDK. It's MORE than annoying to me considering the amount of money that I paid for the thing. I should have ponied up the extra $100 for a Detroit Locker. Trust me, while I paid a shop to install it, I verified it was there when I put on my aluminum diff cover.

There should be an L in the gear ratio number. ie "3L73". If it simply states 3 73, it's a one leg. Also, as previously stated, there should also be a second tag for the use of limited slip lube.
