Can someone help me, im trying to figure out how I go about changing out the driveshaft on an 86 300zx non-turbo. What do I have to remove to get the driveshaft out?

 

it's pretty simple. Jack the car up (safely), crawl under it, and unbolt the driveshaft from the differential (near the rear of the car). This should have a number of bolts that hold it to the differential. After unbolting that, pull the rear of the driveshaft down (push forward towards the transmission and it should come down), then pull the driveshaft out of the transmission.

 

Make sure the car is higher in the rear than the front so transmission fluid does not come out when you remove the driveshaft.

 

But dont I have to remove the exhaust pipes or anything like that? Can I do it without removing the exhaust?

 

you should be able to.
