 Subject: Amsoil additive no help

Message:
I recently changed diff. oil in my 1999 4x4 front and rear. It does have LSD in rear and was making a rough grinding noise when oil was warm and you made a sharp turn after coming to a stop.
I used amsoil 2000 75-90wt oil, which the ad says you shouldnt need a friction additive. Still grinding. I then added a bottle of amsoil friction additive. Still grinding. I then drained oil out again and refilled with amsoil and added a bottle of mopar friction modifier additive. Problem solved. Anyone else had this problem?

Neither Amsoil nor Redline require the additive.
I know dozens of guys on this site using Amsoil's
gear lube without the additive. Maybe someone
else can respond that is currently using Amsoil.

Are you sure no metal particles fell out when you pulled the diff cover? I know when I switched to Amsoil, the reg 75W-90 not the Series 2000, the limited slip was working way better and engaged much more smoothly. I have sold plenty of this diff fluid with Amsoil's modifier and have not had one complaint. Something may have been lodged in the clutches.

Ok Amosoil man just what type of Transmissoin treatment do you offer. I've tried Lotus but it only helps the rough shifting. Not the delayed shifting when the auto is cold.

I am not familiar with LOTUS (except the cars).
Try Auto-Rx® Transmission Cleaner (www.auto-rx.com)
I have recommended their products multiple times on this site. The owners are reputable guys! I know many people that have used their products with no problems.
IMHO, they offer the best flushes on the market.
From my personal knowledge and per their website, Auto-Rx is a synthetic, biodegradable, highly effective, safe cleaner. Auto-Rx® Transmission Cleaner works as you drive. Residue and build-up are liquefied and gradually removed by the transmission filter. Auto-RX is gentle, slow acting, and thorough. I know many vehicle owners that have used it and no one has reported any problems.
If anyone decides to use this Auto-RX product ...
... (For the record ... I do not sell it) ...
... FOLLOW THE DIRECTIONS RELIGIOUSLY.
I wish that I sold it ... but it is a proprietary product.

I screened the oil when I drained it, no particles found.I'm not trying to put down amsoil products. I just found that the mopar brand friction modifier worked for me when the amsoil brand didn't. I don't know why. I just want to let anyone who is having noises such as mine and did try amsoil with no change, to try what I did before they take their truck in for a major diff. repair.
p.s. I do intend on changing my trans with amsoil becase I feel amsoil does make a good product.

Whenever you change gear lubes and install anti-friction
additives I do know that you need to give it time to work it's way
into the clutch packs.
Never had a problem with any of the Amsoil products.

Dr. D After I added the amsoil products I took the truck out and did about 10 figure 8s in a parking lot and drove it around 200 miles over the course of 2weeks without any improvement. I changed the oil again as a last resort before I was going to take it into the shop for repairs.I know this all sounds very strange but all I know is that it worked for me and im very glad i tried it first.

I just added AMSOIL 75w-90 series 2000 to my 2003 RAM 2500 HD with American Axle 10.5" rear that dodge says does not require any friction modifier. I have seen a 1 MPG improvement but notice a slight grinding noise when turning from a complete stop position. no noise with original oem fluid.

Message:
AMSOIL Synthetic Gear Lubes DO NOT require the use of this additive. However, not all differentials respond the same and if chatter is noticed, the addition of AMSOIL Slip-Lock should eliminate it. For chattering differentials not running AMSOIL Gear Lube, this product is an excellent solution to the problem.

AMSOIL Slip-Lock Differential Additive
Effectively Eliminates Gear Housing Chatter
When making a turn, the outer wheels of a vehicle must travel faster than the inner wheels. It is up to the differential to act as a balance arm, establishing constant equilibrium of torques and forces between the left-hand and right-hand driven wheels. In standard (or open) differentials, power is directed to the wheel offering the least resistance. This works well when making a turn, but in a situation where one wheel is lifted off the ground, it causes the suspended wheel to turn while the other remains motionless.
Limited-slip (or positraction) and locking differentials are traction-increasing devices. Locking differentials transfer all available torque to both wheels. The teeth of the spider assembly engage with those on the locker clutch, causing both axle shafts to operate as one. Locking differentials don't allow one drive wheel to spin while the other remains stationary. Instead, they keep both wheels in drive mode, but unlock to permit different wheel speeds when turning. The engaging and disengaging of the teeth on automatic locking differentials often causes a banging and clunking sound. Manual locking differentials usually use an electric motor or vacuum diaphragm to engage the locker, reducing this noise.
Limited-slip differentials allow different wheel speeds when turning, but when one wheel loses traction, greater torque is transferred to the wheel offering more resistance. Limited-slip differentials make use of friction between clutch plates, as opposed to the meshing teeth employed by locking differentials. Transferring less torque per side, limited-slip differentials are generally smoother and quieter than locking differentials, but still sometimes "chatter" when transferring torque to the wheel with traction.
In some differential applications, a friction modifier additive is necessary to reduce chatter. AMSOIL Slip-Lock Differential Additive is formulated with advanced friction modifiers and is designed to eliminate gear-housing chatter in cars, trucks and SUVs equipped with limited-slip, positraction and locking differentials. It also reduces the banging and clunking associated with automatic locking differentials.
AMSOIL Slip-Lock Differential Additive is formulated for use with both synthetic and petroleum gear lubricants and safely replaces manufacturer recommended friction modifiers. Its convenient flip-top dispenser provides quick and easy application to the gear housing. One four-ounce bottle of Slip-Lock treats differential capacities of two to four quarts. It is not for use in automatic transmissions or other applications requiring ATF.
NOTE: AMSOIL Synthetic Gear Lubes DO NOT require the use of this additive. However, not all differentials respond the same and if chatter is noticed, the addition of AMSOIL Slip-Lock should eliminate it. For chattering differentials not running AMSOIL Gear Lube, this product is an excellent solution to the problem.

DIY Helpful Information
For those of you thinking of changing your own fluids (DIY) ...
Helpful Differential Recommendations:
-Flush (drain) as much of the old fluid out.
-Differential fluid capacity depends on ring gear and axle housing size.
-Do not over/under fill differential. This could mean a capacity difference of a quart or more and may cause overheating problems. (See the owner’s manual for proper fill level)
AMSOIL gear oils are formulated with friction modifiers for limited slip differential applications. There is no need to add limited slip or additional additives.
-After changing the differential fluid, drive the vehicle in 7 or 8 figure eight turns, so the new lubricant can work its way into the axle assembly.
