Hey everyone,
I'm wondering if there is any guides/diagrams on how the setup for the spacer configuration/center bearing mounting should be for a lowered IRS?
Story so far. (I have owned the car for a few years 100,000kms on it in my time and suspension was already in it) I had the center bearing replaced as it had failed - Used Repco as replacement. It failed after 1 week of driving. Repco then paid to have another installed under warranty, this too also failed in a week. Repco then paid a Diff shop to replace it again and diff shop used a Burson's center bearing. Diff shop also re-balanced and checked driveline and I had the gearbox mounts replaced as well. I have no idea how the config was of the spacer/mounts.
This worked for a little while however under heavy acceleration I still got a vibration. I did some forum searching and found a thread about the spacers under the center bearing. I moved the spacers on top (lowers center bearing and makes the angle straighter) of the mount plate and then FIXED!
4000kms later, center bearing failed again! Diff shop just replaced this last week under warranty (I also got a rebuilt LSD put in at the same time, axles repacked uni's etc).
I want to see if anyone can shed some light on what angles or any other ideas for me to check out. I dont want to be going back again in another 4000kms.....the diff shop said they think its okay......
I have checked the mount and the spacers are in between bracket and mounts. IRS marking facing front of the car too. (unsure of positions after the first few bearings replaced....)
its a 99 vsIII v8 Statesman with IRS. I believe its on super low king springs in the back. The car does tow occasionally or put the bike racks on.
I did do a search and found some similar problems and a diagram as to how to spacer appears it should be -

Mine is setup with the spacer on the outside bolt. So reading this thread - im not sure now if there is meant to be a spacer at all (i thought the IRS cradle wouldn't changeno matter the car height where solid axle does change?)
The phasing off my shafts are not 90deg out - they are the same at both uni joints. - however i have no vibrations as the car sits - just chewing the rubber around the center bearing.
