I THINK I found out about the lsd in my truck.

[Okie-Go]

I talked to a man today at Houston ring and pinion to let him know about my lsd. I told him about the synthetic fluid as I tow alot. He said if I take the synthetic out and add 1 bottle of friction stuff for every quart of oil it would work. He has had about 15 rams complaining. As per him the synthetic is too slick for the clutches to grip. I may get rid of the synthetic,I need the lsd. Btw he is checking to see if he can get a locker like he put in my 93 chevy half ton. I wonder if I go with regular fluid and change more often would I be OK?

Okie, I hope it works out for you. Keep us posted. As for me, I still have the original gear lube and only have Amsoil in the engine. I think I want an ARB air locker. I spend alot of time on really tight paved roads with hairpin turns so tight I have to do a three-point-road-turn, to get around the corner, and I don't want to be dragging a tire around or stressing my axle with a full posi rear. What is your opinion?

I'm with Extreme1 on this issue. The friction modifier is as the name implies. With too much in the rear end you would never have the clutches locking up. That is one of the reasons Amsoil's gear oil is advertised as not needing the friction modifier, its pretty slick already. Its a balancing act between too much where the clutches never work and not enough modifier and you feel the clutches grabbing in a slow turn on pavement. 1 to 1 1/2 bottles for a 70 series Dana and 1 1/2 to 2 bottles for a 80 series Dana has worked for me. Experiment with the modifier till it feels right to you. Do not forget to do the figure eights to work the clutches, if you don't it may take a while to get the clutches to work right... ... ...

Oh yeah, the manual on page 3-190 says 10 to 12 slow figure eight turns... . Pete

WAY too much additive! REAL bad advice. While the fiction modifier is compatible with your lube, you do not want to go much beyond 5-6%. You will be diluting the lubrication and stability properties of the real end lube. Stay with synthetic if you tow and care about durability and maintaining your warrantee. You can get synthetic lubes that need modifier (eg. Amsoil; not the 2000 stuff) and most of the ones that say they are designed for LSDs still need some.

I added too much modifier on purpose for a while in order to eliminate the limited slip completely. (It is a pain when you drive off road on a slope). But I only had to add 3 tubes to open up the differential completely. You can test for this by jacking up both rear wheels and turning one by hand. If the other wheel doesn't spin, you have an open differential. I went back to straight Amsiol 2000 with no additive once I got tired of spinning out on ice. The LDS now works perfectly when I ride empty. But I would follow Extreme 1's advise since there seems to be a lot of variation between individual differentials in these trucks. You may just have to tweak the amount of modifier for your truck.

Lockers work great if you are willing to spend the money. But I don't think that it is wise to mess around with lube chemistry outside of the manufacturer's specifications.

I agree with you. I don't want mine to be locked together except in a spin like slick grass or mud. I want one wheel to spin a time or two then kick in the other. The guy said the rearend I am referring to is a Detroit locker. He is checking to see if they make one for the Dana 80.

Newf Limo,
Opinions? Are you sure you want opinions on lube? #ad

Seriously, Alot of Rams (and my fiancees Dakota) came with diffs that have too much additive. Do a search of the archives, this was discussed recently.

If running a synthetic (fresh change), drive around untill you feel/hear the clutches gripping. Then add friction modifier a little at a time until it goes away. Some guys repor not using any modifier with some synthetic lube and the LSDs work O. K.

A bottle per quart is not only real expensive, it is way too much additive.

It's my understanding if you have an open diff. and you turn the wheel, the other tire will spin in the opposite direction. If you have limited slip the opposite tire will spin in the same direction. At least, that's how it works on mine.

Dan -- After loading up with friction modifier I could only spin one wheel at a time. The other one never moved. Only did this once though. Now that I'm back in LSD mode both wheels spin in the same direction as you say. Anybody else care to comment?
