Rodeo knocking noise

Dave,
Check your leaf spring bushes. Wear on these could be causing a metal to metal contact.

I just saw in a 4WD Mag buying guide that the AFAIK Rodeo cab mounts can fail.
Have a look at em.
Regards Philip A

also have a look at the tail shaft centre bearing if they have one.
cheers

Hi David

I have 92 model With 275,000 on the clock. Suggest you have a look at the centre bearing on tailshaft & its rubber mount, check uni joints . Also the rear wheel bearings only seem to last about 100,000 Ks then you start to get a bit of vibration & noise coming up via gearstick. Spray a bit of CRC or lanotec on cab mounts one at a time & recheck if noise goes away. Also check exhaust rubber isolators & if it if hits against anything enderneath while you are giving it a good thumping & shaking around.
Hope this is of some help.

Cheers Bungarra.

Maybe totally off beam, but have you changed your LSD oil recently?

My old Jack, 1988 LS 2.6L, used to grumble and chatter from the diff when the LSD stuff in the oil wore out. This was most obvious when starting off and doing a right or left turn, such as at the lights.

Have you checked the rubber Donuts that hold the exhaust up to the body, could be the exhaust system banging around?

Dave, no soln offered, and different area.
Ours started just as we set off to Cameron corner area. Sounded like tappets, but why only in the 2500 -3000 rpm range?
Local mechanic easily found the errant pipe vibrating against the firewall, (when we got home).
[Comic relief was the intent of my post: ours is a 2001 build, so thanks to the more serious replies. Shall keep a watch].
Jeff.
