November 2014 , brand new differential according to elite motors the rework update cclip etc.. all done by fiskerNot likely. If it is loud on deceleration then it is likely a pinion issue. Depending on exactly when it was done it may not have the latest pinion rework done. What was the date and where was it done?
Yeah, that's too long ago. The pinion rework was not developed until summer of 2015. Most likely the pinion is the issue.November 2014 , brand new differential according to elite motors the rework update cclip etc.. all done by fisker
Could you explain the piniom rework? It this crushing the nut? Or something elseThe clip might of been replaced but the pinion rework might of not be done or done correctly. I'm not even sure at that time Nov 2014 the rework of the pinion was being done. If you just started hearing the whine on decel and didn't have the noise back when the RDM was replaced the pinion nut is coming loose. .
how do you usually do it for you customers? , i assume fisker has the torque specs so they torque it to the right setting ..When it comes to the RDM or any cars differential to tight of pinion nut is just as bad as a loose one. I feel the only real way to properly rework the RDM it should of gone back to Tremec and have it rebuilt by them .
When I spoke to my CSP about this issue, they claimed that it would lead to a catastrophic failure. The RDM would eat itself up over time and that none of the parts could be used as rebuild able cores. Very $$$$$ if not caught in time. The whole RDM needs to be taken apart and redone to fix properly.how do you usually do it for you customers? , i assume fisker has the torque specs so they torque it to the right setting ..
what worse could happen , if i can live with the noise?
i drove the car over 600 mile highway speed 75 mph for hours ..
is this differential reparable? , giving the fact was opened again by csp where csp didn't find any thing wrong where he can see, so it could be bearing?I am able to outsource all of the bearings in the RDM as well as the motors forward and aft. Pinion bearings and races we have Timken in stock as well as motor bearings. They aren't cheap but a heck of alot cheaper than the new RDM. We replace all Traction motor bearings during rebuild and any time a pinion nut has loosened it gets new pinion bearings and races as they often discolor (a sign of heat).
Please help me with a differential scheme. I have the same problem with the noise but now as I speed it gives me a mistake limp failure. sorry for my EnglishI am able to outsource all of the bearings in the RDM as well as the motors forward and aft.
