GQ - Vibrations when turning and at take off and slow acceleration

[Pauls4x4]

Hi all,

Starting to get stuck into some of the issues with my recent purchase...1991-2 GQ 3.0 Carb.

Few things I've noticed.

1) if the wheels happen to be turned (this is, going around a corner) when taking off, I notice a grumbling feeling coming back through the steering wheel. It appears to be more prominent the more the wheels are turned. Could this be the universal joints? or could it be something more involved?

2) also when taking off, I get a vibration and noise coming from the transmission (I think) until I get up a little in speed and then it disappears. Only seems to be at take off, if I try accelerating from fast walking pace in second gear, I don't get the same noise or vibration.

3) lastly, the engine is old I know so not expecting miracles but it does seem to be tired when accelerating and really struggles getting to and going past 3500 rpm. That is regardless of whether I'm on LPG or Petrol. I have replaced sparks and leads, distributor and tried adjusting % to TDC but doesn't really make that much if any difference. New spark plugs helped a bit.

Unfortunately, due to finances, I have to do as much as possible as a DIY but these have me stumped as I'm not a mechanic and don't know what might ne causing the above. If any one has any suggestions or could point me in the right direction, it would be greatly appreciated.

Other than the above, she seems to go ok and has been back and forth between Sydney and Melbourne a few times without any drama.

Thanks in advance!

Cheers
