Have any of you ever replaces your rear bearings on a 280zx. I have not started the operation yet but will probably start later this week.
Is there anything special that i need to know about doing it. any special tools? do i need to take the lower A arm off to do this. the way that i look at it now it looks like i may have to.
give me some advice. i was thinking that i should replace them when i am doing the rear brakes.
thanks

i replaced these on my old '80 zx parts car when it was running. it was a real pain in the ass. i left the a arms on and rented an axle puller with the biggest slide hammer i could get. i pounded on the axles for quite a while but they would not even budge. i tried heating the inner bearing race, and that wouldn't work. i wound up torching out the inner races of the bearings. the axles slid out real easy after that. you might try pulling the a arms and putting the whole thing in a press. I don't know if this would work since it is such a big piece and it's awkward to mount in the press. i think using the cutting torch is the best approach, you're guaranteed not to bend anything. just be careful of the spacer that mounts between the inner and outer axle bearings. you don't want to accidentally cut into it. other than that it's a pretty simple job.

thanks for the advice. I have a big enought press at work to do the job thanks to the air force. working on airplanes has its advantages at time. i have access to some tools that i do not have laying around my house.
Thanks
