Picked up the car today

WhiteStallionGT · Apr 14, 2005

After a week of painful waiting, the 4.10s and pulleys are installed.

I drove like a total grandma on the way home, so I don't really know the full potential of these new mods. But I definitely felt a huge difference, definitely.

There is a lot gear whine though, the guy said it was totally normal. When I decelerate, and take the foot off the gas, that is when its the loudest. Will this go away? I'm guessing the gears are just settling in. The gear whine gets pretty loud, but no biggie, I'll just put on some music.

Lol, and my speedometer is way off, its double what I'm actually going. I need to get it recalibrated.

i would take it back to the shop and complain about how they whine, if they say its normal tell them its

alot of people have gear whine, i dont think it will cause any problems, but why live with it if you can have it fixed for free....

congrats on your new gears

DFG 5OH · Apr 14, 2005

i've always heard that if the gears are installed properly there should be NO gear whine, and if there is, you have a problem.

Maybe not, hopefully someone can correct me.

droptopford 5 0 · Apr 14, 2005

i heard that loud gear whine is caused by incorrect backlash on the pinion gear... i know a guy who has whine for about 5000 miles now and is ok... i know a guy who put about the same mileage and ate up his gears...so you decide how normal it is, and oh ya, to a certain extent it is normal because i know ford racing gears have a reputation for having "little gear whine" opposed to other brands, so i guess it could go either way...

1slow95 · Apr 14, 2005

I dont hear any gear whine from my Ford Racing 3.73's.

95riosnake · Apr 14, 2005

I have a tiny bit of gear whine with my 3.55's, but you can only hear it while in first gear, and mainly during deceleration. Can't hear it in any other gears, so yea, I dunno

WhiteStallionGT · Apr 15, 2005

Yeah, during deceleration is when I hear them. I'll see if the shop can fix that, I'm bringing it back for the speedometer recalibration anyways.

VibrantRedGT · Apr 15, 2005

They shouldn't whine and you can romp the hell out of it as soon as you left the parking lot.

Black Stampede · Apr 15, 2005

Yep, if it whines I'd take it back and make em do it over. It shouldnt whine at all. My FMS 3.73s sound great as well.

89MustangGX · Apr 15, 2005

There shouldn't be a LOT of whine, but as you get lower in the ratios they will tend to make some more noise.

The fact that it took a week to do and they are making as much noise as you say, makes it sound like they were not done correctly or by a competent installer.

I would bring them back ASAP. The noise absolutely will not get quieter, and depending on how bad they are, will get louder as they wear!

KingDiamond · Apr 15, 2005

They're not supposed to whine, make sure it's the rear gears whining and not the trans. You're at higher rpms now all the time so tranny whine might be more noticeable.

WhiteStallionGT · Apr 15, 2005

Damn I sure hope they can fix this because the car is definitely faster, its just this noise is ruining everything.

I'm sure someone can fix it, but not sure that they can.

DFG 5OH · Apr 16, 2005

why were you driving like a granny ? Gears dont require a break in period just let em rip.

As far as the wine its hit or miss, depends on how good the install was. I have a set of 3.55 FRPP Gears that I got off Ebay for $100, they had about 10,000 miles on them and I have no whine at all since they have been put it. Then again maybe the exhaust was to loud to hear it

WhiteStallionGT · Apr 16, 2005

This is wierd.

I test drove my car again this morning, and there was no whine.... wtf

Oh and I floored it for the first time after the installation... whoa, just whoa.

DFG 5OH · Apr 16, 2005

Damn i want gears...how much of a difference was it?

WhiteStallionGT · Apr 16, 2005

Like on my way home from work yesterday, i was so tired, and was at a stop sign and wasn't even paying attention, so it turned green, and i hit the gas as i normally do, and my head got knocked back, i was ilke holy**** I totally forgot.

dls322 · Apr 22, 2005

NO You should not romp on them for atleast 200 miles to let them properly set. And if your hearing gear whine, bring it back. There are alot of adjustments that could be off and will severly affect the life of your rear. It will be well worth it when you can drop the pedal and slam you passneger into the seat while smoking the competition.
