after i swapped rear ends (from 3.08 to 3.45) i noticed that sometimes when i try to accelerate my rpms jump up high but i barely feel any torque at all, is this robbing me more of power? is my 305 no match for the gears? im kinda confused and wondering where its going because it sure doesnt feel like its going to the pavement



anyone experience this after a swap? or know where it could be going maybe?

 

I was gonna say that it sounds like the torque converter slipping but you've got a 5 spd... ? If anything higher gears make it easier for less powerful motors to accelerate.

 

sounds like your clutch might be slipping thought... first time driving a stick? when was the last time it was replaced?

 

i doubt it, it pretty much happened right after i swapped. ive been driving the car for about 3 years now. i forgot to mention this though when i swapped the rear ends, i only connected two bolts and one bracket thing, theres supposed to be 2 you know the ones that cover the u joint i think its called. well 2 of the 4 bolts broke off so just one bracket. but could that really make a differ?

as far as the clutch ha, prolly never everything was stock. you think the clutch would do that?

 

I wouldn't drive it like that, unless you want to lose your driveshaft

 

right on, i understand but that thing isnt going anywhere it seated in there nice and tight. i mean, that is what the torque arm is for, to keep the diff in place. BUT i know its not good but how the frack am i supposed to connect that bracket? i thought about just getting it welded slightly for support i mean hey, safety first right?

 

drill out the bolts and re tap the holes, or take the yoke off your old rearend and put it on the new one.

 

Pinion yoke


yours probably looks a little different

 

+1000 driveshafts flying off are not a good thing.

 

hmm well i tired that i took the bolt off my old one and tired to yank the yoke off but no go so i though it was connected to the whole ring n pinion. dam that sucks, i think im just going to take it in to get yokes swapped and get that thing in there the right way. but is that true? just take that huge bolt off and the yoke slides right off? if so i feel retarded

 

yes thats how they come off. Sometimes they have locktite or something on them and are a little difficult to get off, I use a universal harmonic balancer puller in those cases. Before you go pulling it off and bolting it on do you know how to set pinion preload? If you are just swapping it you could probably get away with just marking it and counting the threads.. also do youself a favor and don't drive the car until you fix that, that's very dangerous and asking for trouble..
