i have some back lash (clunking) in the rear of my 240z

i found that the right hand flange yoke or out put shaft what ever you call it has a lot of side, up and down play. Would this be the bearing if so would i have to remove the diff center to replace. My other option is i have a r180 from a 1976 260z 2+2 automatic in good condition would it just be easyer to put this whole diff in insted ?

What are you driving now ? You didn't say. The diff in the automatic will be geared at 3.54 to 1 . If you are driving a manual 4 speed you have 3.36 to 1 . The lower gear will give you a little more off the line and will lower the top end some. Many Z driver have done this for performance . It is easy to change the diff . Rebuilding the diff is not something you should attempt unless you know what you are doing. Best to take it to a shop for a rebuild. I would just install the 2 + 2 diff. Gary

yes i did i have a 240z

the shorter gears might be good as i have taller wheels so it may even things out for me.

well it looks like i will be changing diffs next week end then thanx man:laugh:

sounds like the diffy mount to me...

i picked up my spare diff today and cleand it and gave it a fresh coat of paint
