your opinion on Genuine gears?

[dov'd85]

ok i have set a dozen sets of toyota's using genuine gears including my own, i just finished setting up my buddies and after a month of wheeling/ daily driver the pinion gear is completely gone 

it was all good when i finished it, everything torqued,back lash was right around 7 cleaned and the shimming was set perfect right around 115 was the total on the shim thickness. all the rases new all new bearings and gear set, the pinion depth was great and the pattern was spot on according to the charts so why did his pinion break? i have around 5 thousand on mine and they are still working great? maybe a bad batch of gears?

maybe a bad batch of gears?

nope they are all like that. Everyone I know that has them has been through a few sets. Not worth it IMO. Just get some yukons or precision gear. have them set up correctly and be done with it. Gears are not something to be skimping on cash for

[dov'd85]

ya they were all set up correctly and that is the first one to fail i guess when mine go bad i will spend the cash on yukons... i new that life time warrenty was a bad thing 
why do they break like that? the ring gear is still perfect and the pinion gear is completely gone

[Gittinit]

The steel used for these gears are either to soft or to hard. A hard ring gear with a soft pinion gear =no pinion teeth. These gears are cheap becouse the steel used to make them is inferior. Just imagine how cheap they could make them if they didn't warrenty them.   This brings to mind that tommy boy movie with Chris Farley/David Spade don't buy those ketchup popscicles ya crazy eskimo!

thats a damn good movie
so is that why no one else warrenties there gears... because they cost more/made of differant material?

Most of the other manufacturers don't need to waranty there products becouse they are high quality rather than crap guarnteed to be crap! If you find a manufacturer of quality componets who dosn't stand behind there product then you need to find a new product. At least your in the right place Marlin stands behind what he sells for good reason =he sells good stuff!

personally i think it is a marketing ploy. it works pretty well actually

[Hottrod81]

They are junk

[Willy Mammoth]

I didn't even get to run them. The ring gear bolts kept stripping out before I could get them setup. The holes were drilled too large so ther wasn't much thread to bite into.

Save your money and get Yukon gears, they are a much better gear.

[dov'd85]

i already have genuine gears and i haven;t had any problems yet.. but my buddy is all pissed off about the pinion gear breaking i told him it was because they were junk.. thanks for the replies

This isn't the set I bought is it 

Just kiddin, I knew their rep goin into it...or were they precisions

[yotaboy79]

there junk the local 4wheelparts has a waiting list to get genuine 5.29's warantied

[toyotajoe]

The G/G R&P are s&*t. I had a set of 5.29's  within 4 months I blew them up. The pinion was fine but the ring look like some one cut the teeth in half. Thats my .02. Later Joe

I wouldn't do that to you, I sent them back to 4wp and they replaced them with Precision Gear. Those were the 5.71's anyway.

4wheelparts... the dumb leading the blind...

That's what I figured mark   I know you have a pretty straight forward and honest way

Now I just need to find another set for the front...

[ksmith]

I've been through two sets of genuine gear's. Front and rear have both been destroyed, on the back I'm not real sure what happened, but they were trashed, on the front I stripped about half of the teeth off the pinion gear, took everything else with it, carrier, quicklok, and ring gear.
