The troopy is making a banging noise reversing uphill.

Thanks John

I have had a better look now that the motor has cooled and the engine mounts look fine and no sign of scrapping on the shroud, or damage to the radiator.

Actually had an engine mount let go on a HR holden many, many moons ago. It made quite a of a mess of the radiator. lol

Josh

Not that either.

I gave every thing a shake but nothing moved right along the pipe.

Good on ya Oldbaz,,,, you waited until I went down stairs to check the other things before you posted.LOL

However,, I did give the tail shaft a bit of a wiggle but don't really know what I would look for.

Which end of the shaft should I look at and what am I looking for?

Boo Boo, old son, where the tailshaft passes through the carrier bearing, about midway along..the mounting between the transfer case & diff. I'm assuming troopy
has one.....oldbaz.

G day boo boo, are you in 2 or 4 wheel drive .regards macca.

Hate to put a damper on things but troopy's don't have centre bearings.

Wish I could help but all the things that I would have suggested have been covered.

Just check the gearbox carrier mount, they can break sometimes and allow the box to move.

Hope you find it

Ok Oldbaz

There may not be a centre bearing, but what I did was grab the 'knuckle' attached to the transfer case in one hand and the tailshaft in the other and there is a very very small bit of play which I am assuming is normal.
Whe I grab the tail shaft and rotate it both ends move at the same time.

ob

Would it go bang,bang,bang,bang as I am reversing up the hill or would it only give the one bang as it goes back into position when I lay off the accelerator.

At the moment it's the bang, bang all the way up.

Boo Boo,

Suggest apply full braking to lock the wheels and gingerly let the clutch out in low (or reverse) gear,so the engine is delivering torque to the transmission but nothing is moving. If you get your noise under these conditions it has to be at the engine and would point to the LHS engine mount. If not it could point to something in the transmission - universals? If you can positively decide it won't occur going forward, I'd be looking inside the brake drums as suggested below.

Cheers

OOps - "I'd be looking inside the brake drums as suggested below." was intended to refer to Crackles suggestion above.

John

I put the handbrake on, the troopy in reverse and slowly let out the clutch. Nothing happened, I gave it a few revs, and still nothing happened.

So based on what you are suggesting and and a few others it could be a dry universal.

Am I getting close? lol

Certainly looks that way Boo Boo. You've eliminated engine mounts as a cause, so that leaves something in the transmission or possibly as Crackles suggested, something stuck inside a brake drum. A universal sounds a good place to start. I'd look for play in the universals by putting the gearbox in neutral and manually twisting the rear tailshaft back and forth. There'll be a bit of slop in the diff, but there should be no play in the universals. To nail it down to a universal, suggest pump some grease into one and check for any improvement. Then do the other. (This won't fix the underlying problem, but should help isolate it.) If no change, you can probably rule out universals. That leaves gearbox/transfer case and rear axle. You should be able to decide if the noise is coming from under you (gearbox etc) or behind you.

Good luck!

John

Thanks John

I was going along with your line of thought until you started talking about transfer cases and gearboxes.LOL

I can only hope it is just a dry universal or something as simple.

As for telling where a noise comes from, well I am deaf in one ear which means I can here noise but can't tell what dierction it comes from, a bit of a pain in neck in situations like this.

Barry

Took a couple of minutes but finally got the joke.

I liked it.LOL

Hmmmm,,,

Does anyone know a good mechanic in Bundaberg?

I'll go to them with a few suggestions of what it might be and hope they don't get too technical. lol

Although your thoughts of what it might be don't sound too expensive!!!!

Thanks for your help people,,it's always appreciated.

I'm going to see a mechanic this morning.

Don't know which one but I'd like get the problem fixed as soon as possible.

Mine does exactly the same.

It is the exhaust downpipe from the engine where it goes past the chassis rail.

Check the gap there, if only a few mils., then when you reverse the opposite torque reaction from the engine slightly rotates it on the mounts resulting in a loud rap rap rap as the pipe hits the chassis.

Thanks for that Boo.
So often the poster (and perhaps the problem) dissappear without trace.
