pparaska Posted April 29, 2003 Share Posted April 29, 2003 HI Peter, Wow, it's been a long time since I saw you post. Did you change the pinion flange when you installed it? I'm wondering if the crush sleeve and pinion bearings didn't get pre loaded correctly if that's so. I've heard this can be a problem when changing a flange. BTW, do you have any pics of your car?

Guest 3154tm Posted April 29, 2003 Share Posted April 29, 2003 this is not the first time this problem has come up. does anyone out there have a repair operations manual that would show the correct procedure for r and r of the pinion flange and seal? is it simply a matter of replacing the crush sleeve and pinion nut and retorque to the correct spec? or something else. for driveshaft info try drivetrain.com. there in las vegas. thanks. frank Quote Link to comment Share on other sites More sharing options...
zcarnut Posted April 29, 2003 Share Posted April 29, 2003 Nissan does not use a [replaceable] "crush sleeve" to set the pinion bearing pre-load on the R200 diffs. This seems to be a commonly misunderstood fact about these rear ends. The "crush sleeve" method of setting pinion pre-load is commonly used in Detroit differentials so people just tend to assume that this is the only way to accomplish this. Nissan uses a fixed-length collar with a certain thickness shim to set the pinion bearing pre-load. As this fixed-length collar has a similar appearance to a "crush sleeve", the rumor persists. Indeed, when replacing the input flange and/or the pinion seal all you have to do to re-torque the flange nut correctly. This can be also be verified by reading the Nissan factory manual. Replacement of the flange nut is recommended because it is a lock-nut. I always record the force to requires to rotate the input shaft before I remove the flange nut (with an inch-pound wrench). Afterwards, I check it to see if it has changed. It's not exactly the same as measuring the pre-load, but it's better than nothing. Quote Link to comment Share on other sites More sharing options...
Guest 3154tm Posted April 29, 2003 Share Posted April 29, 2003 steve, in my case i'm talking about the R230. is it the same as the R200 with respect to this fixed length collar? thanks. frank Quote Link to comment Share on other sites More sharing options...
