Import S13 Posted November 1, 2012 Share Posted November 1, 2012 Got a vibration under acceleration and noticeable at anything over 40kmh. This has only started after I had a service and new castor rod bushings, front tyers and front drive shafts. I've tried putting the same tyers on the back and nothing changed. Tried pulling the front shaft out and the vibration is gone while it was out but back now that its back in. All the parts in the front end are tight. The stag is lowered and the new drive shafts sit on a slight lean, can this cause any issue? Can the transfer case cause this issue? Its a s1 RS4.

wolverine Posted November 1, 2012 Share Posted November 1, 2012 ATTESA won't be like the difference in the rolling diameter of your front/rear tyres. Ideally you want to change all four.

Import S13 Posted November 2, 2012 Author Share Posted November 2, 2012 I have the same rolling diameter all around and all 4 of my rims roll and ballence perfect and they are all the same offset and width. I had brand new tyers on the back for a month with the fronts being a little older and had no issues. I then changed to the same brand all around and all are new ATR's on the car with the same size tyers and still have this issue after having the drive shafts and castor rod bushings replaced. I drop the shaft and the problem goes away but I've put it back in as I didn't want to heat up the transfer case too much.

Import S13 Posted November 2, 2012 Author Share Posted November 2, 2012 Can this be related to a transfer case or diff issue? Link to comment https://www.sau.com.au/forums/topic/412874-stagea-vibration/#findComment-6606297 Share on other sites More sharing options...
Race__24 Posted November 2, 2012 Share Posted November 2, 2012 I'm pretty sure that dropping the shaft will not heat up the transfer case, in fact it will do the opposite. The rear wheels are constantly being driven by a mechanical connection, a clutch pack is used to engage the front shaft. The clutch packs will be doing less work without the shaft in there. Bleeding the Altessa system may help. Also using a better oil in there may help.

zoomzoom Posted November 2, 2012 Share Posted November 2, 2012 Cars sorted now Any update on what is was? To be clear, the problem went away when you removed the transfer case -> front diff shaft?

Import S13 Posted November 2, 2012 Author Share Posted November 2, 2012 (edited) Raised the car an inch and half to level out the BRAND NEW drive shafts. Problem was still there but felt a little better. Shoud also help with the life span of the joints. Took the new drive shafts out that also had brand new uni joints. Got my old uni joints and found that they where 2mm longer then the new ones which seem to be fine for skylines but not Stageas. Recond the old joints, fitted them and car feels better than ever. There was enought movement in the new joints to cause a vibration under acceleration. Live and learn.

Problem went away when we removed the drive shaft to effectively make it RWD Link to comment https://www.sau.com.au/forums/topic/412874-stagea-vibration/#findComment-6607117 Share on other sites More sharing options...
Race__24 Posted November 2, 2012 Share Posted November 2, 2012 How did you recondition the joints? I thought they were a throw away unit Link to comment https://www.sau.com.au/forums/topic/412874-stagea-vibration/#findComment-6607400 Share on other sites More sharing options...
KiwiRS4T Posted November 2, 2012 Share Posted November 2, 2012 How did you recondition the joints? I thought they were a throw away unit A lot of joints are not made to be seviceable such as the front driveshaft universals but shops can machine them out and put new joints in.

What would be a ballpark price for this? Link to comment https://www.sau.com.au/forums/topic/412874-stagea-vibration/#findComment-6607533 Share on other sites More sharing options...
Import S13 Posted November 3, 2012 Author Share Posted November 3, 2012 I got new drive shafts and joints for $500 Took them back and they recond the old ones for free due to the stuff up. They said they dont normally recon them as its just as easy and faster to replace them.
