even though many try to make it out to be some exotic creature it is just a vehicle..service it , drive it and treat it like you would anything else..your grandpa can probably teach you these things if you don't already know
Gotta love the CJs. So what are the specs on it? I know you said it has the I6 but what tranny, gears,...?
These things do have some quirks and a few weak parts so as others have said, treat her kindly. Some of those are known to have weak transmissions and there is a design flaw in the rear axle making it prone to breakage so be careful. Find out as much about her as you can so you don't have any surprises. Hopefully grandpa already took care of those issues. Good luck and enjoy. Share more pics!
As for basics you should know, I have already mentioned some but you need to know basic maintenance. How to change all fluids, a tire, do a tune up... get yourself a good Chiltons manual for the CJ and play sponge. Get to know your Jeep inside and out.
What are your plans for her? Daily driver, trail runner, rock crawler...?
I don't know what tranny she has but I know it may not be to great cause my grandpa gave me an extra. I know I have to re gear the rear end cause its off with the thrifty ones that are on it.
It's going to be my daily driver. I hope to learn a bunch more in the near future! I'm not doing anything drastic to change anything, just everything running & looking right then ill be done!
I'm guessing then that it's the POS T4 or T5 that was common that year. Be carefull with her as those trannys don't like abuse. As for regearing, you need to find out what gears are in the axles first before you think about it. Keep in mind that both axles need to match. Have fun with her. You should start a built thread to document what you do.
