The passenger side engine mount cops a beating in the TD42, as the hefty torque is trying to rip that engine mount apart, so I would try to keep the heat shield in if possible, or change the engine mount out for a stronger aftermarket version.....
Most people with the TD42 have had to change out that mount at some stage if they have kept their truck for a little while
My old GQ had a vibration like you describe, and mine ended up being part of the front drivers side A pillar metalwork bracing being cracked ( just like the inner guards do too ), and the harmonic vibration was causing it to vibrate at low speeds.
I only found it by taking the guard off and looking, as the noise was driving me nuts .. I looked for months till I decided to dismantle, but i was fairly sure of the region the noise was eminating from.

@drgtr I found this article insightful.
http://store.uucmotorwerks.com/articles/gear_rattle.htm
May or may not be your specific problem but could be. @garett put new clutch in and solved his prob?
Would help if we (or I) knew exactly what type of clutch is factory standard in TD42T. Anyone know? Mines 2001 Y61 and yes has the gearbox rattle at low revs under load.
What is the charge? Eating a meal? A succulent Chinese meal??

Thanks Plasnart
I have the gear roll over gearbox chatter noise on low rpm 1st and 2nd gear before the larger tyres.
So Im aware of that rattle and not fussed by it as its normal for TD42t.
This one is different.
Its like something is hitting the body and chassis rail in a vibration way
I cant feel it through the body or steering wheel.
Reminds me when I had my 200 sx. Same sound. Really fast light vibration.
Ended up being rear diff mount rubbers were shagged. Hitting the underbody. like a BRRRRRRrrrrr sound

I been looking under the car all day. Cant find anything.
Would the rubber part on top of the spring cause the noise if half of it not on the coil spring? Just kinda dangling?

pretty sure the spring mat wouldn't be the cause of this noise, they are pretty cheap and easy to change though.
might be easier if i popped over for a test drive on the week end.
if its worth doin its worth over doin

Cheers Mate. Sounds like a plan.
70 percent of the time Its fine
but I think that 30 percent I hit the sweet spot and it does it.

Its definitely the motor vibration making something hitting or making that noise.
Does the engine only vibrate sideways? not back and forth.

Bloody all sorted. My mate found it
Bloody Muffler vibrating against the towbar underneath. When I got under the car I moved the exhaust but clearly didnt move it enough.
He noticed the mark on the muffler and was adamant. We cabled tied it to test and yep. Couldnt get the sound to occur.
So he had modify the hook where the exhaust mounts onto. Ill take a pic tomorrow.
Funnily enough when I moved it by hand to test. I can make it touch the towbar but that was like 12cm worth of movement to even get there.
Vibration and harmonics does move things good lol.
Hopefully the pic and this thread will help others.
Always try the simple things first
