Rear differential swap?

[10gaOkie]

I am planning to swap in another rear third member into my 99 T4R SR5 4x4 due to gear noise. My axle code is A03A. I have a 98 T4R 2wd that has the same A03A code on the door that I am planing to use as the donor. Am I good to go? Or should I do anything else to make sure they are the same ratio.

Not pointing any fingers but there are alot of IDIOTS on this forum that like to comment when they should keep there mouth shut. Count the teeth on the pinion and ring to make sure there are the same amount. Toyota has a habit of not matching up the code and and gear ratios. That code could mean you have a 4.30 or 4.10 or a 3.90 gear ratio.

You can either count the teeth or
Jack the car up and see how many rotations are happen in X amount of time...(i count the teeth when i changed mine...)

I read on Zuk's site that the actual ring gear is different thickness for 2WD and 4WD, are we sure they line up exactly the same once installed? I think I might have asked that question before in an old thread, but I don't remember the answer.

Who p1ssed in your corn flakes?? Before you start insulting people, at least check your grammar. It's their, not there.

I would hope this would be checked during the swap as a standard practice. You're right, you can do the spin test, but when were talking 4.10 vs 3.90...I'll count teeth to be sure too. Like Mr. Bamf_CT2004 pointed out, the axle code may not be correct, but taking them both out is the only way to know for sure.

I've never heard that, but then again, I'm an idiot. V6, 7.5", 2 pinion, open carrier should be the same ring for either 2 or 4wd.

Oh, you should know you're going to get flamed a bit when someone asks a technical question and you respond with nothing more than "Good to go." You have got to give more than that.

Anyway, 7.5" and you are talking about the front diff. Rears are all 8". And I just checked back on Zuk's site, and it is the 4cyl vs 6cyl that has a different thickness ring gear. No mention of a 2WD/4WD difference.

Chances are they are the same ratio, but definitely double check with the spin test or counting teeth. There are numerous threads here about gear ratio's if you want to read more, but the bottom line is... actually check your ratios before doing anything. As was said, axle code does not equal ratio.

v6 = 8" ring gear, 4 pinion. and yes they would be the same for 2 or 4wd. If you need assurance look for v6 gears there are no 2wd / 4wd options. they are all the same

Actually his grammar was correct. He was talking about people on this forum(being a location). So the usage of there was correct. In this example IDIOTS is where their would have been used. Lets do a practice by replacing some of the words to see if it can make sense. Here in place of there to represent location and he for their to represent person(s).

a)Not pointing any fingers but here are alot of IDIOTS on this forum
still makes a little sense.

b)Not pointing any fingers but he are alot of IDIOTS on this forum.
does not make sense.


sorry but you broke out the grammar police first

Even if it was incorrect, this is the www. can be just as lazy and wrong as you want when typing. LOL, LMFAO, FTW, IMHO. but I also agree it seems like someone pissed in his wheaties this morning.

***For those that want to say I am incorrect, open up Word and copy and paste the sentence and see what the gammar check tells you. English is not my strong point so I verified with three online sources as well as Word*** as to not to continue to Hi-jack this thread all other differences can be addressed in PM.

***2nd edit*** was looking at the wrong portion of his sentence, as you can see by the examples I stopped at forums after the first there and thought that was the one in question. :ybrick::bash:The second "there" is the one that is incorrect. It should be "their mouth shut"

OP- either spin tires and count rotations of driveshaft or when you pull count the teeth to be 100% sure.

You should stick to answers to mechanical questions. Stay away from the grammar questions. After teaching English for over 25 years, the spelling is "their" in this context. I still look for my mechanical answers from you and others. You know a lot more about mechanics than I do.

 

[JohnsD90]

Since when are internet forums known for their proper grammer and punctuation? Unless you write in sketchy craigslist scammer english, its not really a big deal. And now b*tching about the improper use of "there" put the OP (original poster for you that want to complain about using acronyms) further from the answer to his question. So instead of having a pissing constest just help the guy out.

yesssssss. i was right. DUH. Dr. Neimczyk would be proud.


BUT. i had the same question. even took it to yota dealer, and my personal master mechanic (lexus/yota). even he could not determine w/out pulling the 3rd. so when i put my aussie in i checked. 4.10 just as suspected. but confirmed.

measure twice, cut once . . . dont waste ya dollars. check first. it will only cost you some gear oil.

I don't know why so many people flame on here for not having perfect grammar, but since we're on the subject...

The first "there" is correct. "Their" is not correct in this instance because this type of spelling is for when they posses something - as in, "Their" car won't start or "their" gear ratio is the same". The word "there" refers to an object's existence or location as in "there" are a lot of idiots on here.

The second "there" should be "their" because it indicates possession - as in they should keep "their" mouth shut.

The 3rd "there" should actually be a "they're", meaning "they are".

Thanks guys for sharing your opinions in answer to my original question! On the other hand, it's a shame we have to wade through all the BS to sort out valid answers to a straight forward question. I had planned on counting the teeth during the swap but just wanted to line things out before hand and be sure.

Thanks again,
Chris
