Well this is scary enough for me being it is a BIG change. But its for the best right. I am dropping Blue off @ a buddies house tonight after work. He is going to install my 5.29 gears & rear Detroit auto-locker. The last time I was without Blue was when I had to leave it at a shop to have the timing belt & parts replaced. Well my buddy told me that I should get a less expensive brand of 75/90 gear oil being there is a 500 mile break in period for the gears. I went down to the parts store and they only had 80/90. I asked the counter CHILD and he told me to go to a lube shop to get synthetic oil. I know that synthetic is the best BUT the oil is for the break in period and will just be dropped in a couple weeks. So I ignored his wierd advise and just got 80/90. Should this be ok for the new gears during the 500 mile break in period? After we drop the break in oil I will put something else in but I want a few suggestions. What brand is best and should I then go with the 75/90? Thanks

I think it would have been more appropriate to have your text "blue" as that is your name...just thought I'd say that.

Good luck with your new gears and rock on

I did have it blue but to dark of blue. so then i went to sky blue but it was still on dark blue being i didnt delete the font color settings. but i didnt figure that out til i made it red and then i was tired of editing over and over. So just for you I will make it sky blue and I to will be happy. lol

 

The 80W90 will be just fine. IIRC, that's what the Toyota factory manual says to use and that's what I used to break my gears in. After the break in I filled my diffs w/ Mobil-1 synthetic 75W90.

 

Cool thanks for the info.

 

Break in should be done with the more frictive regular gear lube because it will allow enough heat and similar for the breaking in.

Switch to synthetic when you get them broken in at 500.

Gears and lockers may actually make it more than just big.

 

Form & function not form over fuction as its been. Cool huh!

 

Who did you get the gears from? Are you just swapping out the thirds?

 

What was the decision to for the DETROIT?

Why did you skip ARB?

 

Got my gears from Reider Racing. they are Presision 5.29s. Just the gears not the 3rds. Blue

 

Lack of knowledge on the matter I guess. Blue

 

Well, I'm sure you'll get some pep back in the rig, should be alot easier to turn those big tires!

 

hey , BBB, how much did you pay for the entire set up if you dont mind me asking.

 

should be a nice setup!

 

$9hundred something. Pisses me off though. I ordered everything for the v6 and my tech buddy called me this am to tell me they sent the 4cyl master install kit. So the rear wont have the complete master install kit. I hope it all works ok. Blue

 

Well I picked up my runner tonight. Its not as peppy as I assumed it would be. I mean it does take off easier but I figured it would be higher rpm's off the line. I guess I should give it a day or so before really judging the results. I will get back to you guys soon. Blue

 

Cheers man...glad to hear it! Let us know how you like it after awhile, it'll be interesting to see how your mileage is after all this...congrats!

Glad to hear that you got your 4Runner back. Go to an empty parking and just let her rip!

 

Hopefully, you're following proper gear break in procedures so they will last.

 

I completely forgot about that, ignore what I said.
