I mean LOUD- like a train. They're Richmond 3.55s put in by a highly recommended mechanic. He asked me when I first went to him whether it was a track or street car. When I told him "street," he said I would not be happy. I'm not.

Mechanic apologized. Said he'd yanked the chunk and measured twice- wasn't happening. Said to get some different gears and he'd do it again. Driving back from the shop, I had dogs barking, car alarms going off, and everybody looking. So much for my "sleeper."

Question now is what to do. Thought Richmonds were THE gears to get. Hunt for Ford gears? What about other manufacturers? Found 2 at "Gears Are Us": US Strange and Motive Performance. Will not buy without a recommendation. This is an 8" rear, btw.

Appreciate any help. On the bright side, the new engine is running great.

Richmond are good gears. Sounds to me that he didn't install them right. What was the backlash set at?

Is the sound constant, or does it go away coasting?

Jim,

I've installed a few sets of Richmond gears. The latest we're 3.89s in Melissa's '66 and they are nice and quiet. The Richmond gears have to be set up differently. The instruction sheet included with Richmonds explains it very well and shows the contact pattern required when they are set up. My guess is that your mechanic didn't read the instructions.

I hate to pick on your wrench but I've used quite a few sets of Richmond's and never had a niose problem. I just did a set of 3.55s in an 8" and they're quiet like a mouse. I don't even use the proper tools either, just a torque wrench, grease and some paper !

I bought a set of Richmond gears for a 9" 3.55. I could not get them quiet. I had another professional set up the gears and still noisey. The third company I went to said that the Richmonds were known for noise. He installed another of gears which I cant remember the manufacture and they were noisey. I went back and they got me some Motor Sport gears and that took care of my noise.

Thanks for the replies-

Steve L- It is only noisy when there's a load. Coasts quietly (might get me in and out of the driveway at night).

Scoop, Steve W, and Larry- sure you must be right. They're not in right. From the looks of his shop, this wasn't the first rear he'd set up but maybe he'd never seen a set of Richmond instructions. I didn't have the sheet for him. (What's different about installing em, Steve?)

Funny though- my first inclination after hearing the car was to go to another shop. There's one here in BR that 9 outta 10 will mention when you ask about gears. He's high but his rep is that its done right. Called him and asked if he'd have a look at the chunk. Told him they were Richmonds and he said nope, wouldn't have anything to do with em- too noisy.

I'll call Richmond and get him some instructions.

thanks, guys-
JimO

Steve L is onto your problem and it aint the gears .
I've never looked at Richmond's instructions either.

I've always heard Richmond gears are noisy, so I've steered clear. FRPP gears are the quietest. Cost about the same too.

I had US Starnge 3.25 gears installed in my 8" last spring. I am very satisfied with them. They are quiet. I had them installed by a shop that does nothing but rear ends.

I've set up new and used gearsets and never had any noise problems. Except for the first one I did, and we didn't measure pinion depth. As long as the pinion depth is set to what is etched on the gearset, all your bearings are adjusted right, and your backlash is okay, the gears should not be noisy.
If they are as noisy as you say, you'll probably be experiencing premature gear wear soon!

I've got the same problem in my fastback. I had 3.50 traction lock setup by a highly recommended mechanic. I get a whine from them when there is a load put on them (i.e. not coasting. When I coast there is no whine). The only problem is the guy who set it up for me is about 180 miles away and I don't feel like listening to it for 180 miles. I guess I could remove it and take it to him but I shouldn't have to go to that trouble. I was thinking about taking it to some place local and then see if the guy who set it up would pay part of the bill. I figure I used my time on the first install but the second install should be on him.
