  1. I would be concerned running it without the drive shaft yoke in place. While I like the idea I don't know enough about any damage it could cause or fluid loss. Thanks
  2. Hi mate, all mounts have been replaced. No noticeable difference
  3. Hi mate, thanks for the response The driveshaft is custom made by Hardy Spicer with new universals. The previous shaft was a replacement and turned out to be bent and out of balance. Changing made no differnce. As far as I know the diff is in good condition. No noises and traction lock function well. Rear brakes are drum. I haven't run with the wheels off yet but will try that on the weekend. For some reason removing and replacing the drive shaft has made it worse. I did remove the cross member and rear shock mount to remove the FMX extension housing but there is only one way to replace it. I will check that the pinion angles are still matched.
  4. Hi mate, yes a new tailshaft/driveshaft. I had the same problem with the previous driveshaft which is why I've replaced it with new good quality uni's. I must be close because what ever I did has affected the vibration (worse). Actually to the point where I am afraid to sit at that speed for fear of throwing the driveshaft. As I have disturbed the rear shock mount I will check the pinion angles again just to make sure nothing has changed. Juts need to be away from it for a few days.
  5. Well, an update. I had a new bushing fitted to the rear of the transmission, as suggested. There was a little play, and I was happy to eliminate this. Not only did it not fix it, it's now worse. This is doing my head in. It's not an issue with how I mounted the rear uni, as I triple checked it. I have to be close, as it's something I've disturbed. Both uni's are new and fitted by a reputable company. I'm thinking of taking the tail shaft back and getting them to check the balance and uni's.
  6. When I replaced the flex plate that I had damaged I told the engine shop bloke that I had replaced it. He said If I bring the old and new flex plates he can balance against the old. I had already thrown it out. Still kicking myself.
  7. I've just jacked the car and confirmed that there is up and down play in the yoke going into the rear of the transmision. On the weekend I will get the rear out and have the bushing replaced. I'll report back once I have an outcome. Thanks for all your help
  8. You are getting a little out of my area of knowledge here. The internals were supplied including harmonic balancer and flex plate. Pistons and rod were balanced separately. I understand the crank was balanced with the flex plate and harmonic balancer in place. The old flex plate had some metal remover during the process. Not a lot.
  9. Both the flex plate and harmonic balancer are new. When I told the company that internally balanced my engine that I had then replaced the flex plate afterwards, they said it should be balanced again. The engine vibration is not that significant, but something I would like to tackle at some point. Thanks.
  10. Sounds great. I will replace it regardless so at least its eliminated. I just need to source a bush.
  11. I'll be checking that first thing on the weekend. As I'm not a transmission man, just confirming I need to drain the oil, remove the housing, and a press to change the bushing? Assuming its worn.
  12. Don't be sorry. I'm really glad to have the input. The angles are parallel. Car on stands, digital protractor set to zero on the pulley and taken to the diff is also zero. As I haven't checked the car is level, I can't say what the true angles are, just that they both match.
  13. No, that's something I haven't checked. The yoke appears to be in good nick and I've replaced the seal so there are no leaks, but I haven't checked for a worn bushing. That is new territory for me. Is it easily replaced? I'm getting a little excited....
  14. Hi mate, I am using a digital protractor and I set zero on the front pulley. Then when I take it to the rear pinion it is also zero. Makes it a little simpler then using maths :) Yes, using wedge shims. I have 4 sizes 1, 2, 3 and 4 deg. I didn't know what tolerance was acceptable so used trial and error.
