Noisy NEW Diff Gears 4.56

[toslow]

Yea it really is not right when someone takes money and don't give you what you pay for.

Then not to be accountable for the workmanship makes it even more crappie.


Good luck. And I hope they find the the reason why an fix it.

If you wanted to sound like a pursuit vehicle, a siren would of been cheaper! Good luck.

Nope I wish something that fun.. Durango, 31" tire. Its a 2000 with 103k on it I have had it since it was born.

Just bought a new TT and didn't want to pop for a new TV. actually purchased one that the D' would pull OK.

Now its just a third rig so i figured put new gears in it to give it a little more life with a load. WOW what a difference. It hits 2800 -3k 55-60 (no OD) just perfect for this setup.

I've got reservations all over this summer and I have been out in my trailer 8 times since 2nd week in Feb!! This is one reason i haven't bean pushing the shop too much to replace it. I don't want be without it and I don't really want to do another break-in! ugh. I don't have time - Its summer!!

Don't know the particulars but what is it that you would you be running 456 gears?

This was before your reply.Sorry getting ahead of myself. You said "don't know if it's used as a tv" So it is not your's and you are helping out or did you do the gear swap?

The op had a gear change done by a shop, and they howled from day one. He showed pics of wear pattern.... crappy set-up...... everybody's trying to give him a little incite so when he approaches the folks that did the job, he'll have some ammo to get it corrected.

Sorry bob i thought you were asking. OK OP just for me to learn something. What is this 456 in? Don't think it is a tow vehicle nor an RV.

My understanding is he's had it since new (2000/2001) Dodge Durango and I guess he just wanted to wake it up some. Hope he doesn't need to make a coast to coast trip....be spendy!

[mike.t]

Thanks bob. That 456 will wake it up and correct your are don't go far;o)

its been many years since I adj my gears in my 57 chevy, I did it by feel and grease and had no noise, it sounds like the set up was wrong . and why did you change from stock?

[coffeeguy57]

No drag racing for me. I'm using this as a TV fr my Forest River TT . The 4.56 livens it up a bit for towing. Cheaper than buying a new rig, I just broke it in at 103K miles.

They definitely do not have the pinion depth set properly. This has to be done first so the pinion teeth are contacting the ring gear teeth at the proper angle and pitch. This will cause the noise if not perfect. This job requires a knowledgeable Technician to get it right. Driving it will only cause a bad wear pattern to form on the gears. They may never be quiet if driven to much. In my 40 plus years as a Master Tech I only knew a few guys that set these up correctly.
I wish you luck.

[mike.t]

Any local speed shop should be able to set the rear end up. Where about's are you located? It will liven it up a bit however your mileage will suck big time and expect not to go very fast.

I'm in Eugen Oregon. It does well pulling the TT keeps it right in the power band @ 55- 65. It holds od fine th straight flat at 60 so I'm good. Mileage sucks anyway while towing a wall back there.

i got a buddy in that neck of the woods, don't know if you know him or not.

his name is mark mcnutt

Just got my rig back, shop replaced the rear ring and pinion. It is much quieter but still has noise at highway cruising speed. It of course goes away if i pull it out of gear, accelerate or let off the throttle.

Shop explained it away as "normal'"with a higher ratio gear set. Of course they did this the last set as well. Shop Manager did say the pattern didn't set right on the first set.

I have a feeling its just going to get louder as it did before. At this point it has about 100 miles that the shop put on the gear set. I may take it somewhere else to take a look.

He's obviously a scam artist.
This is funny to no end.
I've got 534 gears in a car I have and you cannot hear any gear noise what so ever!
Btw, I didn't notice but did they replace all the bearings in the rear end ? Those early 2000's Durango's had bad bearing issues.
