how difficult would it be to swap an 82 280zx rear end (diff, cv shafts, possibly control arms and brakes) into a 280z? I was at a rally school this weekend and my rear end is all clunky and rackety and noisy. i know that the zx's has cv shafts in the rear, so that would be desirable. and as long as i was at it, it would be nice to take the brakes so i could have rear discs. or is there a different rear end that would work better (300zx)? or am i wasting my time?

 

Level of difficulty is always relative.... Difficult for an auto mechanic would be a different difficult for your mom. Do you know what you are doing?

Does your 280z have an R200 or R180?

 

its a 2+2 with a r-200. as far as difficulty, i can handle some minor fab work, and i am up for a little challenge

 

If you are swapping an R200 into a car with an R200... it's a direct fit. But swapping actual differential pumpkins isn't going to solve the "clunk." The clunk is caused by a worn out half shaft and/or diff mount.

 

true dat no need to swap **** just fix the clunk you wont gain anything by attempting the swap you said other than a speedo that no longer reads the proper speed haha. also you mentioned brakes i assume you wanted the rear disc's ? yeah wont work sorry!

 

ok. the clunks and rattles i was talking about are from worn bushings and such, and i was just wondering if the suspension on a zx was any more robust than that on a 280z. i need to fix my differential clunk (plan on fabbing a r/t diff mount) and replace probably all of the rubber in the rear end with urethane. oh and do struts and springs all the way around. thanks for the replys!

 

The zx cars have a completly different suspension than the s30.

 

ok thanks!
