How to verify a locking rear differential?

[sag2]

Hey Sag,

Was in the dealer the other day getting my EGR cleaned out (shocker there huh?) and I told them my truck was 'binding up' while in 4WD even on the snow and ice. They (technician) told me it was because of me having a limited slip diff's front and rear. Does that sound logical to you? I can see the rig binding up on dry ground or ashpalt... but on snow and ice too? This is first time truck has seen snow and ice as it spent its first year down in Arizona way.

I think Bubba answered it. No limited slip in the front, and the binding you feel just may be a front axle shaft U-joint.

OK... thanks bubba. that is exactly what I was thinking. appreciate the reply.

Easiest way is to PM the last eight of the VIN and we can verify it.

Sent you a PM on this, thanks!

"rear end squirrelly on ice"



The Detroit TrueTrac/SoftLockers do that. While under load going at 65 mph, abruptly take foot off gas and the sudden removal of torque will cause the rear end to want to fishtail. It's unnerving to say the least if you're on a snow covered road and have that happen.



It's best to install one of these diffs in the summer so you can get used to the effect on dry pavement, so you know what not to do on packed snow.



On the other hand, the fulltime nature of the Detroit is nice on everything but snowy freeways. No switches, negligable binding on asphalt, always works.



I switched my offroad truck rear diff to an Auburn to avoid just this situation. I keep the Detroit loaded pumpkin on the shelf in case I blow up the Auburn.

I may need to add something for snow plowing, not sure what is best in the rear and or front for that but while plowing I will need to make sharp turns.

Any suggestions appreciated.

You're welcome. Again i say how much calmer this forum is compared to the other. I will be joining here soon.

The truck was in Canton Georgia but they sold it before I got back up there. They also had a 2007 with the 6. 7 but I was looking for the 5. 9. Go here to see what other inventory they have:



Cherokee Chrysler Dodge Jeep | Serving Canton, Woodstock, Jasper & Marietta, Georgia



However, I found a 2007 5. 9L Cummins Black QC Sport, (34,000 miles), that you may be interested in located in Gainesville, GA. I really need to sell mine first so I decided to pass on it so here's the link:



2007 Dodge Ram 2500 Truck $30,845 - Hayes Supercenter - Gainesville, GA 30504-8210 Dealer



(The Sport package has the body colored bumpers which look great in my opinion. )

Is what Dodge called the Anti-Spin Differential Axle the same as 'Limited Slip'?



Thanks

 

[SRadke]

That's correct

I think "Limited Slip" implies a clutch pack system and Anti-Spin is a different animal.

GET IT! Change your order now…….

The anti-spin differential is not a limited slip. It is a torque biasing differential, Quaife has built these things for years, and it looks like AAM is either using a Quaife unit, or they have copied the design. Torque biasing differentials have no clutches to wear out, and should last as long as a standard open differential. DC is using the Quaife brand units in the SRT-4 and I believe they also use them in the Viper. I have heard chatter on the board of people having problems, but I really think it is caused from improper additives, as the torque biasing differential is not a LSD you should not add any LSD additives, or use gear oil with the additives already in it. In the owners manual it recommends "GL-5 SAE 75W-90 Synthetic. Limited-Slip AAM Rear Axles DO NOT REQUIRE a limited slip additive. ”

I went to change the oil in my rear diff and was surprised to find out it was a standard diff. What are my choices for upgrading to a "limited slip diff" ? I understand the difference between the AAM and Dana styles. Do I really need to use the expensive oil that Dodge sells or can I use a good quality syn 75/90 gear lube? Thanks in advance.

I was interested to learn a little more and found this:

I am guessing this is the style were talking about. Interesting that it's listed for use in front axles too.

THANKS this was good to know. My 03 has the 11. 5

Yes you can order it in the front also you can all so get it positive track
