I am getting a set of FRPP 4.10's installed in a week or so. Honestly, I am a complete newbie on gears and do know what is what. The shop told me I will need a new pinion bearing, pinion nut, Gear lube and friction modifier.

Do the pinion bearing and pinion nut come with the FRPP gears? (Is that why it's called ring & pinion?) Or do I have to buy them elsewhere?

What brand of gear lube and friction modifier is best? Where can I buy it?

Thank you for your help!

 

I'm having my 4.10 ring and pinion installed also this week. They are supplying all that stuff, I'm surprised your installers aren't. Most of that stuff you can find online or the dealer. People say to always add the Motorcraft friction modifier, I think that has to be purchased at a dealer. Gear oil is up for debate, royal purple, amsoil, mobil 1 all of those seem to be the most common. Hope that helps.

I'd pick that up. Has everything you could possibly need. Just add some friction modifier and call it good

 

Nice kit... thanks!

 

07B,
The term "ring & pinion" refer to the two gears (ring gear and pinion gear) located within your rear axle. The pinion bearings are a set of bearings which the shaft of the pinion gear ride on. Any excess wear or "slop" in these bearings can cause noise or excessive pinion gear movement...all a bad thing. Dependent upon the vehicles mileage, you also may consider replacing the side or differential bearing which holds/supports the differential case within the differential housing. Any excessive wear in these components allow the gear set-up to change whenever a load is applied. The two settings critical to a successful ring & pinion gear change is pinion depth and lash or backlash. Incorrect settings or a setting that changes under load, typically result in noise. These noises are typically described as a whine, howl or whistle and can be heard at various speeds, axle temperatures and/or driving conditions (while accelerating, or maintaining a steady speed, or with the foot of the throttle (coasting).
Also, a properly set-up set of quality gears (like FRPPs) will not, repeat not make noise. If you are told that the "gears have to break-in" or "all gears make a little noise" or blah-blah-blah, you are being misinformed. If you are comfotable with the installer, than go ahead. If not, you may want to consider discussing these aspects and expected results of the gear change BEFORE the car is worked on.. Remember, your spending a good chunk of change here..gettin' it close is not acceptable,
