-- I've heard that they are a real good gear, but that's what I have. - They were new, and howled. -- They were set up 3 times, by 2 different guys (one Guy 2 times - other Guy one time) who have done, probably, 100, or more setups. - still howl at 55 - 60 MPH. -- Less than 200 total miles on the current gears. - Now i'm having them replaced, and don't know if I should switch brands. -- Thanks for the info.I've used Motive Gear in my street car and circle track car. No issues at all. Proper installation is the key with any brand. --

-- Don't know. -- I've spent quite a bit of time searching this topic, and find that Richmond Gears get a lot of bad comments re noise, although many say that is probably a set up problem. -- I'm very interested in all of this, because I'm tired of pulling the rear to, hopefully, quiet it at, normal, highway speeds. -- If this continues, I'll have to go back to Mopar. -- ---- Since it requires very specialized tooling to make gears, I wonder if it matters. --
Car is a "Brand X". --- -- I'm planning to buy a new ring and pinion for My Ford, 8" posi, rear. -- Looking for suggestions re best brand to get. --- Thanks

If you want the run-in gears from U.S. Gear note that they are at least 1.5X the price of the regular ones. They sell the 8" Ford "everyday" gears for $220-$250, but the 8" Ford run-in "Lightning series" are $350-$370. I have never heard anything bad about them, however.get a ring and pinion set made by US GEAR ( NOT US Standard Gear ) -- made in the USA ,,, available from Summit , Strange Engineering , Quick Performance etc . --- Motive Gear bought out Richmond Gear several years ago , box is Richmond but a Motive gear inside--
your problem is a set up issue -- pinion depth shim incorrect or more than likely pinion bearing preload not set properly
if you buy a set of US Gears , they come from the factory with a gear pattern run on them --take a picture of the pattern as this is the gear pattern you should strive for in your set up then get the pinion bearing preload right ( 20-25 inch pounds new bearings -- 10-15 used bearings )

-- See post #17 -- In transit.-- Find NOS O.E Ford gears. Original Equipment gears are always the best, and surely still made in the U.S.A --
