So I'm trying to decide if I should just go ahead and replace the rear end now, or wait until it fails. My car is still mostly stock, but I plan to either run a swap or do a procharger build, or both who knows. Eventually I know I will need a new rear end, but does it hurt anything to just run this one down until it breaks to replace it?

If there's a good chance of breaking something else when it goes, I'll not risk it, but if all that happens is it self destructs and you need a tow, then it seems like might as well wait to actually replace a defective part. Suggestions?

mine made a loud pop and a repeating sound of a pinion hitting the ring gear and didnt move further and then i giggled. didnt hurt anything else on the car. But if you broke it and lock it up and u joint broke then all hell can break. but not likely.

that, and u **** off everyone behind u at the track cause u spray gear oil everywhere. usually right at the starting line. i reccomend pulling it out and selling it

I heard once of someone breaking their 10 bolt on the 3-4 shift. The rear end blew and locked up. The car went sideways into a wall at 120mph. I guess that's WORSE case scenario.

Mine was close to that. Posi blew on hard 3-4 shift, shot me into the other lane at 100+. It didnt lock up or if it did it was only a second. Lucky it was late and no one was coming at me

Sounds like sell it and maybe get another 5-600 towards the 9" I'm gonna put in there. Thanks for the help everyone.

If you dont have a torque arm. Really look at the MWC 9 set up. With a DS discount and other things its light and is an awesome deal. Just have to wait for it.

" If it aint break, dont fix ! "

" if you dont break your part, your not going fast enought "

some one say that back when I first start driving, those quote alway stay in mine mind.

I waited for mine to break and of course it did at the track. It sheared teeth off the spider gears. The car stopped for a second and free reved and the car wouldn't move then after I rolled a few feet I had power again. I realized later that day that it also cost me the low roller Assy in my built 60E which sucked. Because of all this I am now the proud owner of a MWC 9" setp which I absolutely love and a TH400 trans.

If you are going to run more power then now would be the time to upgrade BEFORE you break something. On many occasions the differential will just fail not doing any damage to the rest of the car or drivetrain, but I have seen transmission, driveshafts, and under carriges of cars severly damaged due to a differential failure. If it was me, I would not take the chance.

trans, rear-end ,driveline is the most important foundation for a fun reliable car..

These cars occasionally go into the wall at dragstrips when the rear breaks. You just never know to what extent the carnage is going to be. Bob

Maybe I missed some info, but anyway my .02:

What car?
How much motor?
What tires?
What transmission?

A foot brake auto is much less likely to break axle parts than a stick or a car with a brake. A loose converter helps cushion harsh shift kits...

Lots of cars on stock tires never break the rear axle, even when the dumb *** drunk owner is really trying hard.

Or... you could have a 84 Ford Ranger with a 350 Chevy & 250 cheater plate street racing on a narrow 2 lane road & no shoulder using 28x9 ET Streets on the stock Ranger rear axle and break the ring gear in half and split the case @ 120 mph... with your girlfriend/wife riding along...
