well i put a new rear diff case in since the old pinion ring broke, now when the car is turning the tires screeches and also the diff light and abs light are on. i want to get this fixed soon because the owner of the car wants to get it fixed and sell it. also the abs always kicks in now too, could it be a bad sensor?

 

and i also guess that it's a 4.30 diff ratio would it matter if it's a 8" or 7.5"?

 

what are you refering to as the rear diff case? Third member? Actuall carrier inside?

 

actual carrier inside

 

Are the spider gears seized?

 

nope.. bump any inputs would be great.

 

diff light? Like RR Lock light? Does it have an elocker? Obvious questions but...

 

Are you talking about the rear here? I know you said you meant the pinion inside, did you put the right size ring gear and pinion in? Did you look up the axle code to see what size ring gear it was? Or did you just swap a complete 3rd into it?

Sounds to me like the diff lock is on, if you did put the correct ring and pinion in. Did you mess with the wiring at all when you did the work? Is there any way to get the diff lock light off?

Need some more info I don't think anyone knows what exactly your talking about if you replaced the whole third, or just did the ring and pinion or what the stock gears were before or if you changed the gears or if you put the right size pinion ring in

 

well someone worked on it before me, has factory elocker. whoever worked on it said he put a 4.30 ratio on there, so i guess he found a 4.30 ratio but the diff lock light came on and abs light so i attempted to rebuild the old one but i failed at that because i bought the wrong pinion ring. sorry if i'm not making sense i'm pretty tired right now been working on other cars since 2pm

 

Still a bit confused, before the pinion ring broke, the 4.30's were in and it was driving fine?

 

sorry this is for a 4runner

 

Same thing, I realized that when I posted that it could be a 4runner

 

sorry i'm still new to 4runners, but what might my gear ratios be then? it's a 2000 4runner limited.

 

Do you know your axle code?

Look on the drivers side door jam, right side. On the bottom right of this sticker, it says:

A/TM
A= axle code
T= transmission code

So did it have 4.30's in it and drive fine before?

 

it's not mine, it's my friends dad he asked me to fixed it for him and i told him it'll be my first 4x4 car. so i'll have to check the axle code and transmission code tomorrow

 

The first letter of the axle code is either:
A = 7.5" ring
B = 8" ring

It would help to get some background to know exactly what's in this axle, so any info helps

 

4.30's are stock on 4runners with e-lockers and alloy 16's..I have 4.30's...

Wow I have never seen that site lol and I have been looking at gears for ever. I thought that 4.30's were only on some AT models. Thanks for that link

 

If the tires are screeching then the locker is probably engaged

 

numbers are a04a/a340f
