Drive shaft centre bearing
My SVX is a 1992 model (Australian) with just under 180k on the clock and I have had it since new. Recently developed a clunking noise coming from the left and centre - sounded like my CV joints which was confirmed by a mechanic. Have just had the CV joints and shafts replaced and to my surprise some of the noise is still there but it is very much under left of centre console. After showing it to the repair shop I was told that it is most likely the centre bearing in the drive shaft. The noise seems to be only present when accelerating from stand still and is more readily seen when turning to the right. I had a quick search through the forum and I see that there seem to be two different versions of the drive shaft - one with replaceable bearing and one with NOT.
I am looking for recommendations from any of you who have had similar experience or have had to replace the centre bearing or perhaps it is another problem. |

Re: Drive shaft centre bearing
Have you thoroughly checked your trans and engine mounts? Sometimes a tear can be hard to spot.

Re: Drive shaft centre bearing
Thanks Michael. I wonder if that could be the problem as I have also just noticed that when the car is idling in Neutral it runs nice and smooth. As soon as I put the lever into drive or reverse there is a slight vibration through the whole car.....

Re: Drive shaft centre bearing
I can vouch for the magic potion called Dr Tranny that Carl is recommending. I dropped a couple of tubes down the transmission filler tube and it immediately fixed the shuddering that occurring during slow, tight turns.
This is a fault that the transmission shop and the Subaru dealer couldn't solve. |

Re: Drive shaft centre bearing
Well I have just had a "grease and oil change" type service and the mechanic has confirmed that looks like the drive shaft centre bearing is shot! Anyone had experience replacing and are parts available??

Re: Drive shaft centre bearing
Well guys, I have been snookered!!! As well as the drive shaft my gearbox mounts were shot as well. At that time Subaru had an SVX drive shaft in stock but the gearbox mounts had to come from Japan. We decided to hold off with the tail shaft till mounts arrived so the drive shaft could be sent away to check if it is repairable. Well it is not and the drive shaft from Subaru has been sold. Now it is ex Japan at double the price. Anyone have any suggestions for a cheaper option??

Australian delivered SVXs do not use this type of AWD system - they use the VTD system, which does not use a transfer clutch. I actually had this very issue on my grey SVX - it was caused by a combination of a worn driveshaft centre bearing, worn transmission mounts, and one completely broken engine mount. This caused the driveshaft to be slightly out of alignment, causing shuddering during fast standing starts. I have also experienced the issue of shuddering caused by a binding AWD transfer clutch - my Vortex 4WD Turbo uses the same transfer clutch based AWD system that US model SVXs use. Occasionally, I would feel the drivetrain binding up during standing starts when I was also turning. In my case, an ATF fluid change fixed that, but that shuddering was definitely caused by the transfer clutch. Jason.

you can use a 1999 - 2003 gen 3 liberty AUTO tailahaft. i have used them in place of SVX shafts before with no problems what soever. they should be about $100 from a wreckers. i may even have one in stock at work, if you need one please call me on 02 9600 7066. thanks, Ben.

Re: Drive shaft centre bearing
Jason - mine is exactly the same problem. Both gearbox mounts need replacement and the drive shaft centre bearing is shot! Managed to pick up an SVX drive shaft from the wreckers with a reasonable bearing so will use that. Have given the Hardy Spicer drive shaft experts a challenge to see if they can remove the original bearing so they can put on a replacement.
Thanks for all your tips. Certainly interesting about the Legacy drive shaft!! |
