thanks a bunch

I have read of members on here driving in 4x4 with the rear driveshaft disconnected with no ill effects, so I would think you would be ok.

How far are you driving and how fast. Generally it wouldnt be a good idea to put that much strain on your IFS.

 

One of my friends did it for about 2 weeks I wouldn't say this is a good idea but he did it

 

Bad Idea if you've pulled out the rear third member.
The rear axle shafts need to slide into the splines of the carrier.

If the rear axles are just hanging there- They will probably end up damaging the shafts, rear wheel bearings or axle housing- I doubt the 4 back plate bolts are sufficient to keep them balanced while they are spinning for long period of time.

 

Should be no problem although will the pinion get lubed with the 3rd out?

 

I have a v6 rear third with 4.10 gears for sale! https://www.yotatech.com/forums/f11/...member-119165/
At least you could install it and drive in 2wd until you get your other one set up with new gears.

As said above, you need something for the axle splines to engage and be supported. If you have the ring gear removed, and install the diff, you should be alright (remove rear drive shaft). If the entire third member is missing, I don't think you would get too far (a few blocks maybe).

 

clankity clankity clankity SNAP, bam...SCREEEECHH....

you have to have dif back there to support the axles

I've driven with just the front engaged (blew out a rear ujoin on the freeway! SCARY!!!) ... I pulled the rear driveline and drove the 5-6 miles home but I was very gentle =)

The front isn't designed to be the only thing pushing the truck so remember that when you're taking off from a stop. Personally, I wouldnt do this if I didnt have to (like when you HAVE to drive it home because you blew out a rear ujoint!).

 

Correct, with the 3d member installed, the axle shafts will only have the single bearing at the end of the axle supporting them. They need the splined end in the carrier and the carrier bearings hold that end and the cantilevered force of the wheel sitting outboard of the axle bearing.

 

Yeah, as said - you can disconnect the driveshaft and rive around in FWD, but with no 3rd in there I don't think there's anything to hold the axles in!

As far as rebuilding the rear end, make sure to check this website:

www.gearinstalls.com

I did and decided a rear end is not really a job for an amateur......

 

You could drive around like that. Front wheel drive baby!!! Now you can finally do reverse doughnuts...

 

Well after reading this i thing ill have to fix that hole in my man povered redline haha. cant ce that bad i guess for the time being. i kinda figured i culdent drive it like that. and yes the rear is compleatly out. but dose eneyone no were i can get a rebuild kit for my 4:88? is there like jap 4:88 nd usa4:88s er are they all the same. i dont realy no what i am looking for specificly. but i would like everthing in there to be new. Im not atempting this all by my lonsum i have my uncle helping me hes a mecanic/cop so things shuld go well but i have been givin the task of getting all the prices on the parts we will need.i looked at marlin were i got my clutch but i really dident see eney like seal berings kits or i just over looked them. the ring gear and pinion both say 488 on it with like 32xsomthin they are 488s right?
thanks agean

dont even try to drive the truck with out the 3rd member in it! the axle shafts wouldnt last 5 mins! go to www.marlincrawler.com and the ring and pinion is $195 (MC-14600) and the install kit is $105 (MC-14650)! and make sure u do all the back lash and all that good stuff right or u will wear them out to fast! i would say get someone who is familiar with rears to do it! those part #s are for a 4cylinder! i guess that is waht u have?

 

OK the trucks not goin eneywere i promiss i just wanted to see if it was posable haha .figured it wasent. i did it with no rear drivshaft when i did the u joints and hade to go to my buddys house to use the vice but eneyway... would it be MC-14602, V6 4.88 R&P Gear Set, $195 and MC-14651, V6 & High Pinion Setup Kit, $149?
and what is i hi pinion and do i have one?

andrew

You most likely don't have one.

 

99.9% chance you dont have high pinion. Infact, unless its a 100% crawler I'd highly reccomend against a high-pin rear. They use the driven face to DRIVE.. which is the weak side of the gear. FYI

Anyways....

Call Marlin Crawler and tell them what you have, they will set you up.

 

OK i definently dont have a high pinion.But i still dont no what set up kit to get and was i right with the other R&P? this is what the ring gear says on it the pinion says the same i just couldent snap a shot of it.i hope this stupid attachment works cuz it took me like an houre to get it here. if you cant read it it says 8x39 m/w a little symbole then t488 so if yall cn just make sure i do have 488s that be kool too. and the kit on the marlin website that i cant find lol but yes i hope the pic works..

thanks agean

I can't make out the writing on your picture, but to find out what ratio you have, just divide the number of teeth on the ring gear by the number of teeth on the pinion. (Ex. If your ring gear has 39 teeth, and your pinion has 8 teeth, you'd have 39/8 = 4.875, which are 4.88's).

And if you have stock 4.88's, than you must replace them with Toyota 4.88's (The Toyota 4.88 gear third member is different than the rest, to accomodate the thinner 4.88 ring gear. Aftermarket gears will not fit into your 3rd member.) Your other option is to pick up a used 3rd member from somebody that doesn't have a stock 4.88 (like from hodgepodge79 above). You can re-gear that one to 4.88's with aftermarket gears.

 

ok so i do have 4:88s. the 2 little numbers that say 8x39 are the teeth .pinion is 8 and the ring is 39. nice of toyota to put it on the ring eh? ok so now my problum is how do i no if they are stock? this whole jap gears nd stock gears wont fit is a little confusing? I am geting some on to rebuild it for me so i dont have to worry but i have to get the parts so how do i tell?

andrew

 

No one else knows about what gsgallant was sayin about the whole stock 4:88s nd non stock 4:88s im guessin they are not stock but can some one tell me how i no if they are or not?
thanks andrew
