since the mustang im gonna buy likely comes with a open rear end....whats the easiest way to get posi?? can you put clutches or whatever in your open rear end...?

can you just throw something like this in your rear end and it will just bolt up??

do you need to get some crazy new stuff or what....any info...thanks.

 

You can buy the whole unit and stick in there. but they are usually a 400, 500 bucks.

 

umm yeah here go to summit.com and then search this code.... CUR-94084

thats what im talking about....can i just drain the fluid, take off the drive shaft, unbolt the current rear the bolt that one in and hook up the shaft and fill with some fluid and good to go or is it way more complicated than that?

 

Yeah it's harder. It must be shimed right, and the bearing gap checked. Otherwise you'll end up messing up the gears sooner or later.

 

Don't forget to pull the axles out several inches.

 

If you get a carrier (pumpkin) that is ready to go it is almost that easy. Jack up the car. Pull the back tires and drums off. Unbolt four bolts from each axel and slide them our about 6 inches. Take all the bolts out from around the carrier, drain the fluid and drop it out. Clean up the lube that is left in the housing and then put is all together. Make sure you use fluid that is made for a posi rear end.

 

That part number is for a 9" differential. Unless you have a 9" rear it isnt going to work. Also swaping differentials will require gear setup, including bearing preload, backlash, and possibly a pinion depth adjustment. If you dont know what you are doing, dont try it at home. It will result in some wasted gears. The 9" is the easiest rear end to set up, but also the easiest to screw up.

Swapping out an entire centersection is easy, just like the guys said in this thread already. Putting a posi in an open rear is a bit more involved.

 

The easiest???? Pull out yer carrier and weld yer spider gears together. That will make it a posi real quick.

 

yeah i wouldnt try it anyways.....i just wanted to know how it works....


yeah my grandpa said back in the 60's when he was building race cars they would just weld the whatever together and it would work great. (in the beggining i guess they didnt have a lot of money lol)

 

Ya that welding thing turns it into a spool, not a posi, posi you can still go around corners, spool? ya right... it would be chatter city.
