Gear Oil

[Mr. Sonic GT.]

So this ? is for all the 99-04 people that have put gears in what oil did you use?

 

[scotts99snake]

I used Mobil 1.

 

[Mr. Sonic GT.]

Thanks thats one i was thinking about. Did you add the friction mod to that.

 

[SSChris NY.]

Royal Purple 90w -140w and some ford Traction Modifier

I am not a 99-04 owner but you might want to check out the site sponsor NickT02LS. Amsoil is one of the best oils you can get.

 

[Mr. Sonic GT.]

Well i might have them put in this weekend so maybe something i don't have to order.

I know I am going to get flamed here but no, I did not use friction modifier. I have a friend who works at the ford dealership and he recommended I didn't use it. I cannot remember the reason behind it but I took his advice. I haven't had any problems so far and it has been a few years.

 

[Mr. Sonic GT.]

i wonder if it has to do with the limited slip.

 

[scotts99snake]

Again, don't flame me here guys....By what I remember (and could be totally wrong) something to do with the modifier allowing the clutches in the rear to slip, thus alleviating noise from the rear.

I believe that the Royal Purple comes with the friction modifer already in it....I use RP for all the oil based products in my Cobra....

I have heard the same about RP. I have never heard of the modifier causing any problems.

 

[Mr. Sonic GT.]

So if i get mobile one should i put the modifier in some people say the M1 has it all ready but it could not hurt.

I used Lucas with Ford Fric Modifier. Sonic where are you going for the install?

 

[Mr. Sonic GT.]

This guy his name is bob w.

 

[BubbaStanGT]

not to be confused with george w. . i might be looking to swap in a new set of gears, getting a lot of noise back there lately.

So maybe lucas not so good.What do you think is wrong and how long did you have them.

Good luck with that. I had him do mine last year. That was quite a waste of 10 hours, a set of gears, and $200 for the install. All had to get torn out and redone by a real professional a few months later. Thank god it didn't blow up while I was driving it. :nono:

IDK about the lucas...only stuff I ever used. I had the gears installed 3 years ago and just started to make some ticking noise while slowing down/ making turns recently :nono:.

 

[Mr. Sonic GT.]

So did you or anyone else ever have the barrings replaced when having the gears done.
