I just flipped my jeep last week so i needed a car.. an rx7 went up for sale in good shape so i bought it, today the pumkin or rear wheel gear went out. how expensive is it to replace the rear end?? and has anyone done it?

QuagmireMan

oh ps im parting out my 4.0 90 cherokee for extra cash to pay the bills of the flipping and to fix the rear end of this car. could you guys spread the word about the parts thanks

Hey, what year? Your better off replacing the pumpkin with a used one, itll be cheaper. What went south on your rear gear?

QuagmireMan

i let my friend drive it last night he dropped the clutch but i didnt notice til this morning when i was backing it up then it snaped

QuagmireMan

will a second gen rear end work?

Hades12

sent you a PM on the jeep.

WackyRotary

nope, second gen rearend is not a bolt up. Best to find a 12a cars LSD rear, they are most desirable. I throw out a non-lsd because no one wanted it.

Rx7carl

But what is broken???????????? Axle? Gear? How do you know whats broken? Sounds like you dont really know yet what is actually gone bad.

QuagmireMan

no, i dont know yet. but my guess is the rear right because i jacked it up and when spining it backwards it almost locked up, and its only on the rear right(pass.), so i think a tooth must have come off and is getting smashed as it rotates, cause it was only when i backed up did it snap. so it must have got cracked going forward then snapped going backward. i can take it on a flat bed cuz it will smash my ground effect so i think im gonna try to drive it to the shop.

what do you guys think its gonna cost me?

You'll know if it's a ring gear. It makes this nasty sound that travels through your whole body, lol. Now an axle on the other hand won' t make much noise, it will just quit moving because of the lsd. I've been through both and had my car sitting on jacks for two months looking for a new axle. Found two and have one stored "just in case".

It would probably be easier to replace the whole rear end. Good time to get a GSL rear if you don't have one.

QuagmireMan

it is a GSL rear end. and i tried to drive it to the shop but it was sounding to bad.


how bad is it to replace the ring gear...

and would i be better off getting some rear end that is tougher, eventually if i would go turbo or SC?? and what would i get??

local junk yard will prolly have one. they might not have GSL on hand give it a few weeks they will get one in.

QuagmireMan

i guess im gonna have to go hunt one down, but first i need to find a way to get the rx-7 to the shop, cuz i cant try and drive it, and im afraid if it gets towed my ground effects will get crushed, do you guys know anything that will prevent them from getting smashed?

can you pull the rear end yourself and see what's going on?

Critoris

Don't worry about replacint the ring gear or anything, just put the car on ramps, unbolt your driveshaft flange, pop the axles out and swap it as a unit. Unlike domestic axles, there's no diff cover, the whole carrier bolts into the axle housing from the front. Get some oil and a used unit - takes an hour or two.

??? take them off?

QuagmireMan

well i called to get a flat bed and im going to fill my tires to the max as well as lift up on the car as its being loaded. then drop it off at the shop in town and see what he has to say about it. cuz i cant find any rear ends locally, plus are the GSL 4 wheel disc brakes? cuz mine is and i really dont want to have to change it over again

thanks for your guys input
