My rear - end has a small leak..

And i just talked to a friend about re-doing my gears...


Going back to 3.55, dont ask why, i have my reasons...

I raced coy the other night, and we had the same shift points, at the same speed,

All i really noticed, was the rpm bieng higher at high speeds, and i dont like it at all...



So, i got a friend to do my gears for me.

I just want to know, what fluid do you guys suggest...

Price is no concern. Thanks..

 

Price is no concern. Man, I wish I could say those words!

I don't know a thing about gears, but make sure you add in some FRPP Friction Modifier! :D

 

A girl im talking to is a manager at Pep Boys, im getting it for free thanks..

Im not rich...Ask Christian , or Coy

 

You only need that for friction type limited slips. I don't run it with my Torsen.

 

I'm using (no surprise) Amsoil 80W90 "Series 2000" gear oil. There's a new name for it, and it's been reformulated, but I forget what they call it now. With that in my diff, I need no friction modifier -- but you don't need it anyway, as Dave mentioned.. The friction modifier is just for clutch-type limited slips.

 

John, where can I get some of that Amsoil stuff? When I rip apart the rear in the Mustang, I want to run the 'good stuff'. What are you up to in your engine oil? Still sending in samples?

 

Yes, but only when I change it. As it stands, I just change it yearly. I went 19K last time and that was the end of the year. I'm due in the late spring of this year to change it again.

Go to Amsoil and you can buy it direct. I'm not selling right now, I just did the preferred customer thing. I'll get it for local people at a discount, but I can't get it shipped to you that way. If you're going to change everything over, it's worth having the preferred customer discount (it's substantial). You can often get a trial membership for 6 months for $10 to $20 (I forget how much, sorry). Go to Amsoil's website http://www.amsoil.com and see what you can find.

Or, find a dealer in your area. Considering where you are NOW, that might be difficult! On the Amsoil site, I believe you can search for a local dealer.

 

Thanks, John. I'd be getting it delivered to Michigan and all that. So you change yearly. Man, I don't know if I could ever convince my Dad that that is safe for a vehicle!

 

Royal Purple. Just as good as Amsoil, and PepBoys can get it (at least around here... I'd assume its the same there) Its whats in my diffs...

 

Thanks for all the input...

 

Is Royal Purple specified for extended drain, and for how far or how long? The base stocks are about the same in most synthetics now, it's the additive package that distinguishes them nowadays and that's the key to extended drain.

I agree it's a GREAT oil -- but I haven't heard it advertised for extended drain intervals.

 

You may want to get that checked out, make sure everything is "ok" back there, ya know?


(Sorry, I just had to say it)

 

They recoment change intervals of 12,000 miles. www.royalpurple.com I found it under "why use royal purple" I dont know much more about it since I dont use their engine oil. I only use Mobile 1 in the engine but my Trans, Diffs, and Power Steering have RP in them. Oh and the generator in my trailer...lol...
