replace ring and pinion because of bad carrier bearing?????????
I have been having a bad whirring noise coming from my rear end so I found a local shop where the owner is a die hard jeep guy. I took it in today and he listened to it and said that it could be the bearings going bad but he would have to crack into the diff to see. I just recieved the invoice for parts and it is showing replacement of the carrier bearings, pinion bearings and the ring and pinion itself. The tech said the carrier bearings where pitted real bad, would replacing them mean I need to replace the ring and pinion as well? The price quote was $955 dollars for everything out the door but if I don't need the new ring and pinion it would save me $255 bucks. I am looking for the jeep guru's here to shed some light on this subject for a new jeeper.
Thanks guys this is greatly appreciated.
What rear axle is it? Dana 35 or 44? If it's the 35, don't waste your money on it. There are several places that sell Ford 8.8's as an upgrade for the 35. You could also find a junkyard 44 for quite a bit cheaper, if you can find the same gear ratio. If it is the 44, the worn out pinion bearing can cause the pinion to move up and down under a load, possibly causing a bad wear pattern on the ring gear. Most likely, they are just replacing it to cover their butt for the warranty.
Thanks POS YJ....the rear is the Dana 35 and that seems to be the consensus on what to do with the 35. I was just hoping to get it repaired to minimize my down time since this is my DD. I know it would be better to get an 8.8 or D44 but I just don't know how long the diff is going to last before I can get one of those noted above sourced and put in. Wish I was located somewhere that had more 4X4 shops to choose from.
I would inspect the ring and pinion yourself. The R&P shouldn't have to be replaced due to a bad bearing, however if there are knicks or abnormal wear in the R&P then they should be replaced.
I would ask the mechanic exactly why the R&P need to be replaced.
On another not, a bearing should be a fairly simple job. In fact if it ends up just being the bearings/s I would take the Jeep back, pull the carrier yourself, cut the old bearings off, then have any auto shop press new ones on. Bearings are like 10 bucks each, really not that bad of a job, just requires the right tools.
Freeskier thanks for the reply, that is what I am going to do tomorrow morning first thing, I am going to head back to the shop where my jeep is and inspect everything myself. I had done the outer axle bearings about 6 months ago and the ring and pinion didn't look bad at all when I had the cover off. I would do it myself, i am not affraid of tearing into the jeep but my tool supply isn't what it should be to do anything major. Wish I had a bit more down time from work so I could weight all my options and take my time to repair it.
If you have a socket set, crowbar, dremel, and torque wrench it can be done yourself pretty easily. Then it's a matter of finding someone to press new bearings on, but I'm sure any shop has at least a 12 ton press.
Obviously not everyone has the time or the tools, but def. go check the gears out. Not having to replace the R&P will save you a bunch of money, not just the cost of the gears themselves but the labor to set them back up as no set of gears are allike.
the shape of the r&p depends how long it was making noise.you can just do bearing but the gears were riding in a differant spot so it can be noisey when going down the road.im sure the carrier is shot so putting used gears on new parts makes little sense.the price is a bit high but i can say it should take over an hour to just clean out the grey bearing paste
Thanks guys the quick responses I get on this forum are great, it is really appreciated. I am going to go tomorrow morning and see if there is anything that can be done on the price to get it a bit cheaper. My neighbor is really good with this stuff so maybe I can ask him to take a look at it and see what he thinks.
Freeskier the camera is a real good idea, also I talked with my neighbor and he said it would be no problem to fix it in his garage....for free (well a case of Beer and Steak dinner). He is even going to source all the parts I need, this way I can get my hands dirty and get an education at the same time. I will post up picks of the process once we get it done. Thanks for all the help you guys, once again I don't know what I would do without this forum and the great help.
