Ok, yep I understand that now... so on a moderate 3 inch lift with no extended shackles then wedges are not needed..

Normally the best way to start is no shims. Then if there are problems you can use shims to help. Springs are made differently, some might put the angles perfect others might not. Unfortunately it's never just fit it and be done, there always seems to be a bit of tweaking steering, brakelines, prop angles, trimming body work and bump stop adjustments

You may also need them if a transfer case drop kit was installed 'cos that would point the output on the T'case downwards.
In that situation you'd install them the other way round with the thick end towards the back so the nose of the diff is lifted.

The idea is that the output on the T'case and diff are kept parallel.

Thanks for all the responses, after reading that lot my brain is overheating  :icon_biggrin: Been out today for an awesome day out laning down lincs/leics border, had a passenger in the back and the noise was a little quieter. Ill post some pics on laning trips later. An old problem has arisen again, driving through a ford to wash the crap off the jeep starts being hesitant after a few hundred yards, will keep you all posted.

Look under your inlet manifold for a wee beastie bolted through the gearbox bellhousing and spray it with WD40.
If the hesitation/misfire goes away then the problem is the crank position sensor, it's wiring or the connector.

My water tells me your problem lies there!

I might be wrong but I doubt it!

Having driven it since it went through the water it drives fine now, does the cps get wet and play up maybe? Ill take a look at it tomorrow after work.

Did you tighten the leaf spring bolts before you fitted the wheels or after?

The bolts should have been tightened after the wheels have been fitted so stopping the rubber bushes being in a torsion mode which will result in premature failure

Yeah we lowered the car onto the ground then rocked it side to side afew times then tightened up the leaf spring bolts. Been out laning today and on the way home we got up to 70 mph on the bypass and the vibration is almost non existant  :icon_biggrin:

Just an update for you all, now been a month since I did my lift and the vibrations I had have almost gone. I have got to the stage of no weight in the boot and no fuel in the tank ( shock! ) so to make the propshaft sit at its maximum normal angle and its almost fine. I have had to buy a 15mm spacer for the drivers side coil as the front was on the piss  :017:
