I should have listened to you guys, wasted $350

[spederman]

I read about every gear post on here. Everybody said, get FRPP gears, and you'll be fine. But i wanted 3.90's and went with motive, well now i want set my car of fire and put my car in the bottom of the lake. It whines so fuggin loud that i cant even handle riding in it for 5 minutes.

I spent $165 on gears and $200 on install. I dont know what to do now. The dude that installed them comes highly highly recommended in my area. Every single person in my mustang club has gone to him with no problems. I specifically asked him if he can install Motive gears since they are supposed to be harder. He said he has never had a problem on gear installs. Well, i guess this set of motives the dude.

He put the gears in (2 hours), took the car for a test drive and they whined a little. He asked if thats how it was before i came in, i told him ***** NO. So he took everything apart again and said he would re shim it. He did it again (another 2 hours) and took it for a test drive. They whined ever worse, but he was pretty much giving up. He told me i should have got frpp instead, and told me that actually gears are supposed to whine a little because then you know they are set up properly. Whatever dude. But i watched him, and he said he set the pinion depth and backlash to stock specs.

What do i do now. I dont want to spend another $200 of frpp's and $200 on install. I want to keep 3.90's because i dont want to run out of gear at the track when i get my procharger. Do i chalk it up to Motive gears suck and they whine? But a bunch of people on here have them and say there's are quiet. OR should i call and find a person that KNOWS motive and can re adjust them and see if they dont whine. But then i dont want to spend another $200 on having them re adjusted if it is the gears and not the install.

Save up another 350-400 and get it done with real gears.

Buy the 4.10's and install taller rear tires to compensate and then correct for the gearing and tires using the Xcal2

 

[SaleenGT2001]

my motive 3.90's have been in over a year and dont whine at all! find a better installer!

 

[jasonh_86]

and told me that actually gears are supposed to whine a little because then you know they are set up

I've never heard that.. You might want to find somebody else, this sounds like bs.

I've ALWAYS been told that they SHOULDN'T whine if they're installed properly and that if they do whine, then they're not installed properly.

My 3.73's never whined, helty's 4.10's never whined after install.. So I don't see how your 3.90's should whine "if they're installed properly"

There's a guy in my town who says they whine, but he always does a crappy-ass install and it's never really right.. That's why I never took any business from him, just a load of crap if you ask me

Just find a Ford Master-Tech or somebody with that much experience/knowledge, get them installed and they shouldn't whine.

 

[BaXTeR3221]

First, think about it this way, you only paying for install again. You can sell the 3.90's to offset the price of the different gears.

Also, i had a set of 3.90's in my fox and they didn't whine at all. Sounds like the guy is pretty good, but there are also plenty of people who have installed 3.90's and dont have the whine. Id get a set of frpp gears and have someone else install them, preferably a ford master tech like said above.

 

[DropTopPony]

never heard any negative about the motive gears...sounds like installer error....he can't just give up!!! make him fix it! if he won't, call the BBB.

 

[ocbaud]

i've got motive 3.73's in my truck and they dont whine one bit

 

[Kilgore Trout]

No no no!

Just have the gears reset. It is not unheard of for backlash and preload to have to be reset after a 100 miles or so. This is no big deal and about an hour's work and your installer will have it corrected

It is not that Motive or FRPP whine more or less, it is about the quality of the installation and the adherence to Ford specs.

 

[VTEngines]

It's the install..not the gears.

 

[thomas91169]

It's the install..not the gears.

+1

go back to the installer and either tell them to fix it of get a refund.

gears do not whine if installed properly. even the cheapest gears will last long without whining if done right.

if you do get new gears, find another shop.

Stick around damnit!

I could never understand why people puss out and go with a set of 3.90's when the 4.10's are cheaper and so much more plentiful. Is the need to be different that great? There's next to no difference between the two as far as highway RPM is concerned and the 3.90's aren't going to save you from running out of gear at the end of the track any more than the 4.10's would either.

 

[SaleenGT2001]

i would NEVER put 4.10's in my car, especially with the s/c. i am thinking about going back to 3.73's or higher. 3.90's are a great mix if you cant decide between 3.73's and 4.10's

 

[mity2]

Take it back, and tell'em to do it again.

Any gear, Mortive or FRPP, installed correctly, WILL NOT whinne!!!

If its whinning then its not installed right! take it back!

.....a great mix!?! At cruise speeds, the difference between a 3.73 and a 4.10 gear is all of about 200RPM. Now....explain to me how crucial the difference of 100RPM in either direction that going with a set of 3.90's is going to give you over the other two is going to prove significant?!?

Even with a blown car in most cases, the 4.10 gear is still going to bring you in under the rev limiter. If you're coming in though the traps riding the rev limiter at the top of 4th gear otherwise, your problem probably isn't too much gear, it's too short of a tire. 3.73-4.10 I could see, but 3.73-3.90 or 3.90-4.10 seems like a waste of time to me.

 

[Mossberg]

Yeah, I thought about 3.90s but wanted to stay with FRPP. No regrets here. 4.10s FTW!!!

Hey Mossberg, next time i'm up that way, we need to hook up. I wanna know whats it like to have 4.11

WOW there is another person that sees the light..

for months I have been saying this in every damm " will I run out of gear" thread.

4.10's or 4.30's or don't bother, if you run out of gear go to a taller tire. You can tune you gearing with the overall tire height.

I am with the it's not installed right crowd. take the cover off and run a pattern on your gears that will tell you a lot about whats going on..

one last thing... did you use new bearings.. if not that might be your problem.
