Clicking noise when i 3rd and 4th gear and...

[gnarnold]

Yes a few times until I busted a piston about 50 -60 miles from home .she was loud she was pist but I'll tell you what ........ : she got me home on three cylinders the whole way at about 70 mph from Temecula wine country all the way to Costa Mesa .and that was the end of that engine.
Then it got stuck in 4wd a couple of times cause I bumped it into 4wd

[irowiki]

That would have killed your front diff then.

[gnarnold]

Yes something absolutely died that day .but it was not my faith in the rugged die hard quality of this car.it would not quit .

[Petros]

he may have put a 2wd trans in it as an economizing favor. now is your chance to find a 4wd trans and put it back into off road condition.

[gnarnold]

In my car a 2wd tranny how could I tell
Don't get me wrong it worked in 4 wheel drive
The 4 wheel drive worked
Works how do I know if it was 2wd tranny

[Gottolovem]

I don't think he read the entire thread

[gnarnold]

Trans as in trans axle ok my bad I thought he meant transmission .wheew!
So I'm gonna go down and check the rear diff and see what kind of trouble I can get into .any words of caution .
By check I mean remove that plate to inspect for damage

[Petros]

actually i did not read the whole thread, I was in a hurry. but I saw the criptic message about the mechanic that saved the car by putting another trans in it, but warned it would not have 4wd. Perhaps he got a good deal on a trans with a different ratio and installed it as a "favor", but knew it would damage the drive train if it was used. I have ran across several "fixers" that people have inadvertently put the wrong final drive in it and mismatched the front and rear diff, usually trashing one or the other diff. now if I look at a T4wd where someone says they put a "new" tranny in it, I am suspicious they may have mixed up the diff ratios. too bad, usually they just have to swap out the diff housing so the front and rear ratio matches, that is if the diff in the old transaxle is in usuable condition.

there is some idiot wrecking yard manual running around the internet that lists all Tercel4wd transaxles as "interchangeable" across the years. Just not so, even the gear box ratios are slightly different. they can be swapped if you change out the diffs, but they do not warn about this in the manual, many otherwise good Tercel4wd have end up in wrecking yards because of this. One I saw locally the owner took an ax to the car before selling it, a real shame, it was in otherwise good shape. I can see what happened, trans go bad, searches for a replacement trans, gets the wrong one, the shop install the "new" trans, with clutch and rear main seal, they guy spends $1500 or more on it. A month or so later the drive train bundles up, take it back and the mechanic says, "now it needs a new differential, that will be $1000. those things happen sometimes". in frustration the owner takes it out on the car, and than junks it. Every body panel had ax holes in it, every window smashed out of it.

Tragic by all means .
Speaking of the diff some I'm on the rear one .getting ready to check for damage .now I have losened all the bolts 12 mm on te inside face of diff
When I pull this thing out what's gonna happen .should I mark anything
I meanorry to bother you but the rear diff if I want to check it out to see if there is any damage 1. Are the bolts that hold on the plate on the inside face of diff?
2. Is this a wise thing to do? Thanks

This link will help you understand how to pull the rear axle

[Petros]

you have to pull the left and right axles (remove the backing plate of the brakes and the axle should yank out, after a few whacks with a big soft mallet). than it should just fall out after you break the seal, lots of old oil will come out with it. You will want to check the back lash, the wear pattern on the face of the gears, any "wire edges" at the edges of the cut faces of the gears, no pitting, missing teeth, or scraped up gear faces.

if good, reinstall it with form a gasket (make sure you clean out the housing of old metal shavings and sludge). fill with synthetic gear lube or good quality hypoid gear oil.

when the axles are out you might check the wheel bearings for smooth rotation. If there is any roughness they should be replaced. not too costly, but unless you have a big press to use best take the axle to an automotive machine shop and have them press off the old one and install the new bearing. the FSM shows you how to remove the old collar and bearing using a chisel, do not waste your time trying that, you spend a lot of time beating on it with a big sledge hammer, and eventfully you can work it off. Not worth it, the guy with the press will only take about 5 min to get it off.

if your gear lash is too large, there are places that specialize in installing the shims to get the lash correct. this is a very sensitive adjustment and should be done by an experienced diff person, preferably someone with lots of toyota experiance (the truck diffs are very similar but larger, so if they know toyota truck diffs, they can set the lash properly on the Tercel diff.) they should put in a new input shaft seal when they reset the gear lash.

So you can't just pop the cover off the rear diff to take a look at it?

Nope

[irowiki]

Must be different from those big pickup truck diffs you see all the time then.

[Petros]

you can pull the cover off the front diff to inspect it. But the rear housing is integrated into the axle assembly. you can I suppose inspect it though the filler plug with bore scope video camera.

Drain the rear diff and inspect the gear oil carefully for shavings, falkes or metal parts. If the rear diff turns smoothly, no seal leaks, fill it with fresh lube and leave it. If for some reason you think there is trouble in the rear diff than it has to come out.
