Spider Gears
 
I just got my jeep back (97 TJ) from the mechanic after getting a few things looked at. He informed me that the rear differential spider gears are coming apart. He said I have a few months but will cost roughly around $700 to be fixed. Is this project that anyone has had any experience in doing themselves? If so, what are some things to be aware of? I assume it’s not easy, but is it possible? And if possible, what are some good brands/places to find the replacement gears?
Thanks in advance.

if you never worked on the gears and the R&P i wouldn´t do it alone. ask a friend that has done it before to help you.
if you need to replace the gears i would think about regearing. that gives you the power back that you loose wih bigger tires.

i just ordered some gears from 4wd.com, they have a 10% rebate on drivetrain parts.
they sell gears from "superior".

If you've got a D35 rear axle, now would be the time to upgrade. I'd hate to see you spend $700 to repair the stock unit.

GrnTJ 10-16-2007 09:51 PM

He honestly said $700!? Not $70? Because thats a lot more like it. If he wants to charge you $700 to replace your spider gears than you better tell him to screw off. I had this problem in my Grand Cherokee (same axle) and I ahd to replace my spider gears in it becasue they were cashed. I found some replacments on ebay for all of about $35 if I remember correctly. Its a pretty simple project too. Took me all of about an hour, and its the first time I had ever had dealt with ANYTHING in the differential at all. Deff. do not pay anything more that $100 if your gonna have someone else do it (and thats with brand new gears). Either he figures you for an idiot or there is something more than your spider gears that are gonna be messed up back there.

rketr 10-16-2007 10:13 PM

Yeah, that does sound quite high.

Did the $700 only cover the spiders or were they tossing in a Detroit with it? :D THAT would sound more like $700...

garcia6767 10-16-2007 10:25 PM

Yes, I really don’t see how it ends up being $700?? Is labor usually that much? Also, I bought the jeep used a few months ago and it has been great to date. For a jeep that year with over 130,000 miles on it, it that a common problem? Keep in mind in does have 33in tires and I think, not positive, it has the stock D35 rear axle?

Here are some pictures, if they help.

700 as stated is way to much. Is there something else being replaced besides the spider gears?

garcia6767 10-16-2007 10:46 PM

as far as what he said, and the report he gave me no.

GrnTJ 10-16-2007 11:17 PM

From what I see they look alright. Perphaps a little bit of wear but nothing too bad. Mine had straight up chips oout of the teeth and full on busted off teeth on the spiders. They didnt look too bad. I would absolutley ask if he is talking about simply replacing the spider gears and if he says yes than ditch that guy. He is trying to rip you of BIG time. This is really something you could even do yourself as I stated before too. You could install a locker for that price. Good luck and ask any other questions you may have.

whitebuffalo 10-17-2007 10:24 AM

just weld them together and be done with it :D

seriously though, 700 for spiders is ridiculous

GrnTJ 10-17-2007 10:29 AM

^ Almost said that but I decided to be serious on this one. If you wanted a full time locked rear though then this would deff. be the cheap/easy alternative.

freeagent53 10-17-2007 10:57 AM

axle rebuild
 
Im a inexperienced mechanic and rebuilt my whole rear end for well under 700... the only thing i reused was the housing... i thought it was fairly easy to rebuild.. once i recieved all the parts (ebay) i took me about a day to pull the axle out and take it apart and about another day to put it back together and under the truck..., (keep in mind ive never done this before) - do it your self if you have time... that way you know how to do it on the trail if need be...haha

Tj Bunch 10-17-2007 11:57 AM

You could also put in like an aussie locker for a couple of hundred, I know they are not recomended on the 35's but crap why spend that much on something that is still gonna be stock.

garcia6767 10-17-2007 01:38 PM

I appreciate all the help so far. I think I’ll just end up getting a few more quotes from other people. Anyway, what would be a reasonable price in getting them fixed by a mechanic? Including parts/labor? Any ideas? Thanks again.

Gr3yTJ 10-17-2007 03:23 PM

:eek: wow they're trying to rip you a new one... i am a service writer at 4wd specialty in richmond and the price for SG is $400 for labor/ on any axle and then you just need to pay the price for the gears... which 411s for a d35 are about 135 i think

GrnTJ 10-17-2007 03:45 PM

Gr3y, hes not even talkign about having the ring and pinion replaced. All he needs are the spiders. If you really charge $400 jsut to have those put in than I think your ripping people of too to be honest. I did it myself for $35! Those gears are cheap. Not like they are complex parts. If you are talkin about a whole new set of gears (ring and pinion) than I guess thats decent but not for just the spiders. Id say you should spend about $100 if you where to have a mechanic put them in for you, including parts.

see its not even like that, we as service writers dont make up our own payment ill explain how it works... a shop has its own shop rate or service charge...ours is $79 an hour.....and to replace the SG its an axle assembly which the computer auto charges based on the dif rating of the work.... well for SGs it says about 3.7 hours so 79x3.7=292.3 with tax and brake cleaner and what ever else they use it will be around 300 something the plus the gears which is prolly more like 60 or 70 dollars when you dont get them off ebay.. so sorry if you think we rip people off but thats not the case here


Edit: just checked all data pro... and they charge 4.3 hours to change SGs

GrnTJ 10-17-2007 05:33 PM

I understand. Thats why I never take my stuff to shops though I guess. I dont even have the kind of money to pay for labor costs like that. Im still pretty confused on that whole rating system though. It took me 45 minuted to an hour to get it all done and Im not even a mechanic. Matter a fact it was my first time ever having any kind of differential apart at all. The labor rate seems fair but the amount of time it estimates for the work to be done seems unlikely to me for a licensed mechanic to accomplish the work in.

Save a little more and go for this:

GrnTJ 10-17-2007 06:39 PM

I would agree with you marc but then he'd have to ahve the gears set back up and a whole bunch of new costs come up when you get into replacing ALL the internals. It wont cost much to simply replace the spiders.

myanarchy 10-17-2007 06:51 PM

If you have a few months, find a replacement axle. No point in locking the 35.

If you need to tackle it yourself, other than a torque wrench it doesn't require anything special, or any special skills. Your changing the guts of the carrier, not re-setting gears. Taking your time its only a 2 beer job.

1BLKJP 10-17-2007 08:21 PM

Well looking at those pics I would say that your spiders are pretty chewed up. Did they say how much metal they took out of the dif when they popped the cover off?

As far as getting the spider gears you can find them way cheap anywhere in town or on ebay. Putting them in is a snap.

Put the rear axle on jack stands, remove tires, drums, and diff cover. Rotate axle until you can see the cross pin and the pop it out. Push in on one axle at a time to remove the c-clips. Spiders will probably fall out. Replace with new spiders and put it all back together with fresh oil.

You're absolutely right about that.
:punk:

garcia6767 10-17-2007 10:27 PM

Thanks everyone, I really appreciate all your suggestions and will make good use of them. One more question I promise…if not I’ll start paying you guys ::Danyway seeing as I’m from New jersey and if mother nature is generous enough we get our fair share of snowfall/winter weather. With that said, if I wait till spring to replace the gears, would engaging the 4x4 in the winter have any effect on how much faster they wear out, or would it have no effect? Thanks again!

GrnTJ 10-18-2007 12:20 AM

No effect since they are in the rear. They are always turning anyway.

Vector6 10-18-2007 11:15 AM

an aussie will replace the spider gears for $229. and about 2 hours of your time

I wouldnt recommend a aussie or lockrite for a rear axle if its going to be mostly street driven.

2 hours to put in, 45 minutes to take out once the rear end blows to pieces.
You can't polish a turd man:)

GrnTJ 10-18-2007 04:52 PM

anarchy, if you read my thread you will find that I am keeping my D35 and locking it as well. Not everyone wants a huge rig man. If built properly the 35 can be plenty tough. Especially for the type of mild/moderate wheelin many people do.

You're correct, but you're still stuck spending money on a marginal axle. You still have a weak ring and pinion no matter how strong you make the axles.
I destroyed mine on 33s twice, neither time were broken axle shafts, both times were destroyed carriers and ring gears.
Why not just do it once and build something that you won't have to worry about, instead of building something marginal that will be maxed out with no more chance of improvement?

Just curious is all
