BucketTrucker688 Posted June 26, 2015 Share Posted June 26, 2015 Last year I purchased and installed a reman 4.64 ratio front differential from Camerota Truck Parts who rebuilt the rear with a 1 year unlimited mile warranty. At day 362 of the 365 day warranty and 24k miles I was decelerating off the interstate with a approx. 5 ton load of mulch on and a driveline vibration and gear lash noise appeared. I pulled over and started to investigate...pulled the magnetic plug off the front rears side cover and found metal shavings stuck to it...got it home (about 10 mi from the interstate), removed the side cover and the ring gear was obliverated. So I pulled the whole carrier and dropped a new one in and sent the damaged one back for warranty. They got back to me yesterday and said they will not warranty the failure and the type of damage was due to overload. I honestly feel there was never any overload. This is my only truck and there hasn't been a single person other than myself behind the wheel of this truck in over 6 years. I baby this truck and do not ever ram and jam as I'm the one that pays for and has to fix the damage. In the past year 90% of my work has been asphalt hauling where i rarely leave the blacktop surface and the other 10% being misc stone and soil loads, not very hard on the truck work and nothing iv done should of put any overload enough to destroy a rear. Any opinion on if this is a fight worth battling with them? They said they will refund me for the rear all but the $800 ring and pinion they have to replace and will not reimburse any of the labor. Now if there was an overload would the only damaged part be the ring gear or was this a weak gear that let loose 3 days before Camerota Truck Parts wanted it to?

mrsmackpaul Posted June 26, 2015 Share Posted June 26, 2015 Well it wont be overloaded then and the onus would be in them to prove it was over loaded ?? They will waffle on about how they are experts and have being rebuilding diffs for years and they know whats what and what would you know I hope you have some sort of weigh bridge tickets which will show that in fact it hasnt been over loaded and then it should be pretty clear cut They wont just hand the new center over I feel with out a judge getting involved as it will set a precedence for everyone else good luck with it all and right down every conversation or record them on your cell phone seeyaPaul Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294741 Share on other sites More sharing options...
Dirtymilkman Posted June 26, 2015 Share Posted June 26, 2015 Wow. You'd think a reputable place would stand behind you. Sounds more like ring and pinion weren't shimmed right or something like that 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294742 Share on other sites More sharing options...
hatcity Posted June 26, 2015 Share Posted June 26, 2015 Dumb question-If there was such an overload to damage the inner works, wouldn't the wheel bearings be damaged also?

BucketTrucker688 Posted June 26, 2015 Author Share Posted June 26, 2015 Well my thoughts were a universal should of went before any damage to the ring gear occurred. Obviously The power hits the universal before the diff. And my universals have I don't even know how many miles on them as they were what were on the unit when I purchased the truck 6 years ago but still tight.

Timmyb Posted June 26, 2015 Share Posted June 26, 2015 Is there an agency that deals with this sorta stuff in the USA? In Aus we have consumer affairs which is too protect the consumer, or also the small claim tribunal which I belive is a court system for similar situations.All in all, it's a lousy predicament! I'd arm yourself with knowledge from other differential specialists and try talking to them a bit more. Best of luck! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294749 Share on other sites More sharing options...
theakerstwo Posted June 27, 2015 Share Posted June 27, 2015 What they are talking about is shock load instead of over load like in weight wise.Most rebuilder are same way about shock load.You can look at it and see were it was broken from a strain.But if it has gaulded brgs or gears that were wearing prematurely then its will fit parts fault in my eyes.

BucketTrucker688 Posted June 27, 2015 Author Share Posted June 27, 2015 Yeah they are talking about shock load but the mack 400 specific failure analysis guide line sheet they sent me described it as a "overload" and that's what they say they follow.

gearhead204 Posted June 27, 2015 Share Posted June 27, 2015 huh.... most shock loaded macks ive seen have either broken axle shafts, or trans. main shaft falures. metal fillings and burs sounds like improper assembly and or preload or under/over tempered parts you might have a rockell hardness test done on the failed parts to see if they are in spec. with factory specs. if failed parts are not adequate then i say take em to court 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294781 Share on other sites More sharing options...
b615rich Posted June 27, 2015 Share Posted June 27, 2015 I hate to ask the obvious, but did you escalate with their management? Usually you get the front line answer but almost every company has a flexible process if you push, sometimes even just ask. I would tend to thing a ground down ring gear would be caused by set up or bad part. You would think overloading and or shock would hit a lot of other parts first. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294782 Share on other sites More sharing options...
bullhusk Posted June 27, 2015 Share Posted June 27, 2015 I had a front 3.90 rear go in my western star in May of this year and had my truck at horwiths in Northampton pa, thay gave me this same option to go with that guy you bought the rear from; but after some calling around I bought a brand new one (not reman,new) for not much more from my guy in Bellville NJ Tapco!! The way I feel about rears is like the big 4 ton stone that you beat with a 15 pound hammer for 2 weeks and just can't break it and then a guy comes along with a ball hammer and hits it one time and it splits in half!! So as the story goes; 'it wasn't the one shot from the 3 pound hammer that broke the stone but the 500 shots from the 15 pounder before you got there that broke it'!!BULLHUSK 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294788 Share on other sites More sharing options...
6368 Posted June 27, 2015 Share Posted June 27, 2015 Could have been a high quality chinese ring gear like i just saw a guy installing in his rockwell. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294793 Share on other sites More sharing options...
theakerstwo Posted June 27, 2015 Share Posted June 27, 2015 That is what we call will fit parts. most of them look great. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294797 Share on other sites More sharing options...
BucketTrucker688 Posted June 27, 2015 Author Share Posted June 27, 2015 I was told they use oem parts but yet I recall seeing PAI bearings. So what's the chances of the gear being PAI. never actually looked at it before I sent it back and I can't make it out in my pictures I took as what the numbers and markings are on it.

blackdog2 Posted June 28, 2015 Share Posted June 28, 2015 Camarota doesn't stand behind any thing and way over priced .Went there for a u joint for my super liner didn't stock it and they wanted 340.00 Courvilles 104.00 out the door, Quote Ed Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-294903 Share on other sites More sharing options...
BucketTrucker688 Posted June 29, 2015 Author Share Posted June 29, 2015 Stupid question...would the power divider stuck engaged cause even a slight shock load to cause the ring gear to fail?

gearhead204 Posted June 29, 2015 Share Posted June 29, 2015 i wouldnt say shock load .... but extreme presure on the ring gear yes! this condition would be worsened if the front and rear drive tires are mismatched as far as circumfrance is concerned, because the tires would be traveling at diffrent speeds, but coupled by a common shaft Quote Link to comment https://www.bigmacktrucks.com/topic/40670-camerota-reman-differentials-warranty-issue/#findComment-295029 Share on other sites More sharing options...
