Play in drive shaft and thump under hard shift

frankiev · 03-02-2016, 10:22 AM

I have a thump from under the car when shifting hard from 1st to 2nd mostly . I took it in for an oil change and had the mechanic looked at the trans mount which apparently is ok . He said theres a bushing in the rear support that the diff is attached to that apperars to be cracked .
Is this common ? Im assume its covered under 5 -50 so Ill contact the dealer

My second problem is this . If I let the clutch out quickly so it just engages theres some ratteling that the mechanic says is play in the drive shaft . Is this normal?

You can check yourself to see if you have drive shaft play though it's more likely that's just the flywheel Rattle that you're hearing.

Honestly I'd probably just pay and go aftermarket for the diff bushing. The oe bushing is terrible and a replacement will just fail again, most likely outside of warranty. Unless you plan on selling the car soon get an aftermarket bushing. I have the whiteline bushing on mine.

How do you find the whitelines ones on the road ? Is there an increase in noise vibration and harshness ?

I am planning to do mine on my 2012 car when I fit the Quiafe diff

My car is a bad example as it's built (at least mostly) for autox meaning stiffer everything. Also I'm extremely tolerant of NVH. I can't imagine just the whiteline diff bushing really increasing nvh much at all.

Any time you use stiffer/harder bushings, there will be some increase in NVH.

New bushing seems to be a popular option when modding/replacing diff so a site search might provide some insight. From what I recall reading on here, there is an increase in NVH but most people consider it a small price to pay. YMMV

Called the local Nissan dealer ,said not covered . I found a local shop that will do it for 300 + parts . Seems like a good price
