I didn't go surfing today, because my wife has a sunburn. You married guys understand. So, I finally got the back end up in the air and turned the rear while inspecting the Prop-shaft. Prop-shaft is fine. I don't know if this is a good or bad thing, as the noise is from the rear differential. It is amazing how rear noises can transfer up a tube and make you think its something else. At least I think its the diff, as when I grab a wheel and turn it back and fourth, or grab the prop-shaft and turn it back and fourth I get some solid low-pitched clanks from the diff.
This leaves me with a few questions. Mind you, this is my 1st and only RWD car that has the engine in the front, so bear (bare?) with me.
What is the factory ratio on an 80 Spit? Mine is labeled 3.63 on the underside with yellow paint.
If I get a new one, what ratio should I change it to for FL highway speeds? We have 70+mph, and figure a 3.5k to 4k revs at speed would be great. OD on of course. I don't know what it is atm, as I've never taken her over 55mph.
How hard is it to change the diff? I hear of people swapping them out for racing all the time, so I assume its a doddle, but I've never done it.
Is the diff heavy enough that I will need a 2nd person to help me? I've only got about 18 inches of room to work with mind ya. Ground to frame. Plus, I don't have any buddies that around here that know their rump from their elbow, when it comes to cars, so its gotta be something I can do myself, or I gotta have a station do it. Unless one of ya is willing to come help in exchange for some free surfing lessons :laugh:
What does rebuilding the diff consist of? Again, 1st RWD car that is not Mid or Rear Engined, so everything for me has been transaxles.
Any words of advice or cautions before I dive into this mess?
