A lot of Fieros tend to be street cruisers driven by older guys(at least, every V8 one in my area I've ever seen was driven by someone that was more into car shows instead of running it down a drag strip). I doubt any getrag would last long with a few hard launches on a set of drag radials that hook nicely or a set of stickier slicks. We all know what happened to Jay's 282. :icon_redface: He did have a higher mileage transaxle from what I remember though....a fresher one might have lasted a couple of passes w/ a hard launch.

well, after some debating, ive came to the conclusin im going to not get the race axles right now. first i am going to make a poly tranny mount and lower engine mount and see if tha helps, then i got a few other things in mind i want to do aswell......

OK 1 more thing....... could the car being lowered be causing this??

wait theres one more....

Thursday August 10= Dyno Day for Kuntzie

where are you getting the dyno run done at?

its a secret, no not really, getting it done at F&F

seriously though could the car being lowered + the pwer be casuing axle breakage??

Depends on the angle of attack on the axle now compared to stock ride height. If you are lowering a car I would think it would push the axle further into the yoke. But I guess the question is how far in is safe? That I couldn't tell you without seeing it for myself. You need to ensure you are not damaging the yoke by having the bearing rollers bottoming out when you hit a dip in the road.

Easiest way to tell. Clean out a yoke and axle bearing end...put some modeling clay inside the yoke. Get you and 10 friends to sit on the front end of the car to force it to bottom out...then take measurements of the clearance you have between the bearing rollers and the yoke base. If you are bottoming out then you are most likely fatiguing the yoke from collisions between the bearings and yoke.

ill take some pictures of it the best i can, and see if you see someting odd about it. also what about a shitty balljoint or something else i might be missing that could be causing this?

definately a possibility. i've been looking around at lowering springs for my GS lately and it seems that the general consensus is that any more than 1" lower will cause vibrations during acceleration due to axle geometry being thrown off. i think the fix was raising the engine back up with plates between the motor mounts and subframe or something like that. i haven't actually heard of this being a problem for 1st GEN W-bodies, but i don't know why they would be any different. i haven't had this problem with my lowered Cutlass either; although i've been using the Eibach springs which don't lower the car nearly as much as the Intrax springs.

turbo sedan, i dont even have the intrax springs, i got my springs off a olds 98, lowered the car about 2.5 " in the front,

also the tranny mount on the top of the tranny/ attaching to the x-over, lets say therotically, the tranny mount was not there (mine is but just a question) could that be causing the tranny to move?

holy crap 2.5"!! i've seen pics of your car (looks awesome) but i never even considered that as a being the culprit of your axle problem until you mentioned it...i didn't think it was that low. with your car being so low in the front, i would say that is very likely your problem. if you can, try replacing the springs and see what happens. it might not look as good but it's better than breaking axles every time you go to the track.

are you talking about the crossover pipe support bracket? it's not really a transmission mount at all, so if it's not there the transmission isn't going to move any more than it does with it in place. it probably wouldn't be very good for the flex bellows though.

on a side note, i think the 282/284 5-speed in a W-body could definately use more and/or better transmission mounts. they don't seem to have much lateral support. i've considered trying to fab up a bracket between the rear side of the transmission and the subframe so i could use a solid bobble strut type mount like a Turbo Dodge has. i think even the 282's in the Beretta have a bobble strut type mount on the front side of the transmission.

kuntzie · August 13, 2006, 06:16:32 PM

the best picture i could get currently... the axle looks like this ___----- lol i could definitly see a problem

ya josh, the car sits way too low..... i like it that way though, but i have a low profile jack and it wont fit under the car (on the cradle) i have to use a sissor jack then put the other jack under it.... heres a pic if you havent seen it before.... its not even 1 finger clearance in the wheel well

Invasion1 · August 13, 2006, 06:33:19 PM

take that pic of the CV while running past it with a camera???

LOL worst pic ever..

TGPilot · August 13, 2006, 07:26:08 PM

So if the picture is level then your geometry is extremely off!

Also your CV boot if it is correctly on the axle is Hyper-extended Pulling the CV bearings to the outside of the yoke.
I think I mentioned this when I was talking about when the car lifts on take-off.
Put the proper springs in and run it...bet it works! ;)

Prospeeder · August 13, 2006, 11:52:43 PM

sheesh being that low u must be scared of speed bumps and dips in the road

I definately agree with the others that the lowering might be your issue. I know there are a few 88-96 L67 swap guys around here, and they have to run modified axles in their cars due to the width being different, but I know if they lower their cars with the modified axles they start having problems. The break axles and one guy that I know of actually ruined his differential because the axle was pushing in on it so much.

Raise the front of that car up and I bet the axle issues go away or at least get a LOT better.

muhahahaha Jud.... better get back to the track 108MPH trap!!!!
