Hi all I have just put new shackle plates on the back of my series 3 that are 3 inches longer than standard to give me one and a half inch lift on the axle at the moment i still have standard shocks on the back but hope to get some extra travel shocks from billing next week
The problem is now when start to slow down the prop shaft now makes a horrible (out of whack) sort of noise
every thing seems to be ok underneath ie: UJ's good and all bolts done up
any ideas
Various things come to mind.......
The angle between the UJs is now to great. You may need to get some angled shims to sort it out. The shims fit between the spring saddles on the axle and the springs. You'll need some new U bolts probably and a longer centre bolt for the springs to hold the shims in place.
If you've still got the std shocks you may be fully extending those as well as the vehicle drops its nose as you decelerate. That would give some nice crunchy noises.
Apart from lifting the chassis I'm not sure what longer shackles do - they dont really give you anymore ground clearance - ie diff to ground. May improve entry and departure angles by a degree or two. You can fit a larger diameter tyre to get more real ground clearance, but even that has its limits.
