Author Topic: Broken 4 wheel drive. (Read 8336 times)

Ok, I finally got around to pulling the cover off my front differential. What came out was a shaft that was broken in half, and two gears, or chunks of gears i should say, that were about the diameter of a tennis ball. I will post pics when I get home, but I was wondering what exactly that means to me, what I need to replace, and how much should it cost??
Also, any background on the front diff would be helpful because everything I know I learned today taking it apart.

Oh yeah,
1991 V6 5speed IFS

sounds like the cross shaft and spider gears, dont waste your time and money fixing it, this is the perfect excuse for SAS !!

Yes, ditch the ifs, it will be the gest decision you can make. spider gears are crap anyway, lockers are better.

BLACKDOG · « **Reply #3 on:** Oct 27, 2004, 10:49:35 PM »

how much do spiders cost to fix??

I dont have a choice on the IFS right now If I had money, I would swap it out

i know a guy that is selling a front diff w/ 4.10's for $10

BLACKDOG · « **Reply #7 on:** Oct 29, 2004, 12:13:03 PM »

Really? mine were 5.29s, but obviously not anymore

them's the spider gears all right. if you don't have the $$ for a SAS just stay on the street untill ya do. or you cloud blow some $$ and put in a locker in the front for now.

BLACKDOG · « **Reply #9 on:** Oct 29, 2004, 07:31:22 PM »

86runner, what shape is that diff in?? is it for IFS?? If so, I am interested. How much do you think it would cost to ship to CA??

Man those are some good buy's If you dont want that third blackdog let me know so I can get it...it has the same gearing i do

Hyena · « **Reply #12 on:** Oct 31, 2004, 09:07:35 PM »

Are spider gears the same for the 8 inch and 7.5 inch? Or are they different sizes?

SWAMPER · « **Reply #13 on:** Oct 31, 2004, 09:13:34 PM »

I think their different but I also have a 7.5 so I woulnt mind that diff there

Mike D · « **Reply #14 on:** Oct 31, 2004, 09:35:04 PM »

different

BLACKDOG · « **Reply #15 on:** Oct 31, 2004, 11:05:25 PM »

Thanks for the Link Kyota

Skinny_Pedal · « **Reply #16 on:** Oct 31, 2004, 11:10:42 PM »

dunno. not to much. i can get the link again if u need it

BLACKDOG · « **Reply #17 on:** Nov 01, 2004, 12:15:12 PM »

Ok got some stupid questions

When I have a locker in the rear, that pretty mich replaces the rear gears correct??

Also, I am looking at getting the IFS third off the link Kyota posted up. I had 5.29s and it has 4.56s Will that matter at all?? I know it isnt ideal for bigger tires, but I need my 4 wheel drive back. It is off a 94 v6 pickup.
Will that fit onto a 91 v6 pickup??

KYOTA · « **Reply #18 on:** Nov 01, 2004, 12:26:14 PM »

A locker like a Detroit or ARB replaces the entire carrier and the ring gear is bolted to it, a locker like a Trac-lock replaces the spider gears in your existing carrier. And yes the gear ratio's must be the same front and rear so if you get the one I linked to you'll have to have it re-geared.

BLACKDOG · « **Reply #19 on:** Nov 01, 2004, 01:08:24 PM »

would it be better to get that one regeared? or have mine regeared?? Since the spider gears and stuff basically shattered, would it be better to use a diff housing that hadnt had that happen?? or does it matter?

SWAMPER · « **Reply #20 on:** Nov 01, 2004, 01:09:54 PM »

Yes because then it will feel like your axle want to swap places

I dont think it matters if u use the same one or not

KYOTA · « **Reply #21 on:** Nov 01, 2004, 01:15:06 PM »

Inspect the carrier you have, but I'd guess that since that cross shaft broke, the holes in the housing where the shaft goes is probably wallered out a little. You may be better off replacing the whole carrier

BLACKDOG · « **Reply #22 on:** Nov 01, 2004, 01:20:41 PM »

Thats kinda what I was thinking. Flying metal in small spaces doesnt do well. Thanks for the input. How much m i looking at to get it regreared?? About? I've heard $100-$800 and anywhere in between.

SWAMPER · « **Reply #23 on:** Nov 01, 2004, 01:22:05 PM »

The gears would be like 100 bucks plus the master gearing kit onother 100 bucks plus add 150 bucks or so if your getting them installed by a shop

BLACKDOG · « **Reply #24 on:** Nov 01, 2004, 01:23:12 PM »

ok so 350 or so. Thanks lil swamper. 'preciate it

SWAMPER · « **Reply #25 on:** Nov 01, 2004, 01:41:43 PM »

Im giving you a "cheap" price but its around that ball park also shop around for the install some ppl will jack up the instal price big time man

Mike D · « **Reply #26 on:** Nov 01, 2004, 02:31:15 PM »

you may also have killed some of your bearings

reklund5 · « **Reply #27 on:** Nov 01, 2004, 06:31:58 PM »

I have an IFS Front diff assembly laying outside as well if it will help you out. Its got factory 4.10's in it, but I'll install whatever gears you want if you send me the gears and a few bucks for labor, then send the entire thing out to you so you can just swap it in.

BLACKDOG · « **Reply #28 on:** Nov 02, 2004, 11:43:16 AM »

thanks to all. Lilswamper, if you wanna try to get that 4.56 gear set go ahead. I think I'll have reklund do the gears once i get the money.

Also, what exactly do i need to buy in order to fix this problem?? I have never doen this so i am not sure

SWAMPER · « **Reply #29 on:** Nov 02, 2004, 12:29:35 PM »
