hi everyone, i was hoping that my first post wouldn't be me asking a question but here I am. I have a 98 camaro putting 450 horses to the ground through a m6. Friday i was accelerating on a highway when my car started making a loud banging noise which I later discovered as being 5 teeth broke off the ring gear. i have every intention on getting a fab9 or s60 either this winter or next but just dont have the cash right now. im looking for a new ring and pinion on jegs and their are a few different manufacturers such as motive, richmond, and jegs house brand. is there any one that is better then the other? they are all priced pretty similarly. also i currently have 410s and was planning on switching to 373 because i dont really need the extra grunt off the line and would prefer to actually use first gear for more then 1 second. is it true that the 373 has a bigger pinion then the 410? thanks for any input.

generally strength will depend on the ratio as lower numeric ratios have bigger pinions so yes the 3.73 will be stronger. generally the richmonds, and motive orange box gears are a little noiser as they alloy they're made from is stronger and can cause whine. the quietest gears will either be AAM Motive blue box, or yukon brands

I've personally had great luck with Motive setting up for other people. I have run 2 sets in my personal car also.

thanks for the replies. i just ordered the motive g8 series gears which should be the blue box ones. i also ordered a solid pinion spacer in place of the crush sleave and i found a used diff girdle on ebay tonight for 85 bucks, hopefully it adds some cheap insurance. hopefully this set up lasts longer then the last set. i pulled out yukon gear 411s today and i also noticed i have a new axle in one side. i'm hoping the old one didn't twist and thats why it was replaced.

I used yukon gears.They were recommended by the guy that worked on my rear end.
Really quiet and strong.

The gears that were in my car were only in their for about 5 thousand miles and i had some noise on decel. I was pretty hard on it though so i don't really blame the gears, rather my driving habbits. i'll be taking it alot easier on this next set so maybe i can sell the rear end and put the money towards a fab9 or s60

G8=Orange box, GM=Blue box. I've made a gazillion posts regarding this.

thunderkitt3n

sorry, the box color isn't as easy to remember as the g8 and gm in the part number. i seen you commented on someone elses post about the this and thats why I went with the g8 gears. thanks again for the help. im thinking i should take my 315s off when im not at the track, the diffy might appreciate that lol

I went with Motive after seeing posts about how they were quieter usually and other people have had good luck. Hoping they turn out well...I can deal with some whine but I really don't want them to scream.

I've had 2 sets of g8 orange box motives and aside from a touch of noise they have been great.

I wanted 3.90s and since the only ones you could get were the orange boxes that's what I went with. I knew they may have a little decel whine but whatever. They installed great and had a nice pattern and preload but have a hint of whine on decel which is fine with me again it's expected with the harder alloy. Also the higher numerically you go the higher the chance that gears will make noise so your yukon a may have made noise just because they were 4.10s. Some will be quiet but it's not uncommon for them to make a little noise

i know this is off topic but are all the old ring gear bolts suppose to break when taking them out? it doesnt look like the little bit of threads that did come out had loctite on them.

STOP!!! The ring gear bolts are LEFT HAND THREAD. clockwise to loosen.

thunderkitt3n

yep, they sure are. i wish i would have looked at that sooner. what is the reason they are left hand thread? i wouldnt think they would back out if they were right hand thread would they? i'm glad i stopped after the first two broke. thanks

^^^Reminds me of my first 10 bolt build

thunderkitt3n

ha, glad to know i'm not the only one. thats one mistake ill never make again. no better way to learn then the hard way. new bolts should be here tuesday then maybe i can get her back on the road. thanks for the help and advice everyone. its very helpful to get answers from people who have done the same projects im trying to do.

Put the 4th heat cycle on my car today, no whine that I can hear. Gonna put a 5th then a few hundred of easy driving, drain fluid, then go wild.

Torque arm is certainly hitting body, forgot to clearance it. No ABS actually makes braking feel better too.

Do yourself a big favor and get YUKON gears! They're the only ones that advertise their quiet operation, and you'd be hard pressed to break them (of course in ordinary situations, aside from the general 10 bolt weakness)
