1987 trooper, banging in 4 wheel drive - Pirate4x4.Com : 4x4 and Off-Road Forum

Bossler · 04-08-2005, 07:17 AM

I recently purchased a 1987 isuzu trooper II with the intent of some light duty offroading. Upon driving it in 4 wheel drive, especially when under stress, some 4 wheel drive component bangs and clunks. This is more obvious in 4 low than 4 high. This never happens in 2wd. My friend had a 1990 Trooper II that did the exact same thing. I think it may be the chain is stretched in the transfer case and may be skipping. If anyone has had any information on what this problem may be, or how to fix it, any input or guidence would be much appreciated.
Thanks,
Matt

Its a gear-driven transfer case.

Some more information would go a long way towards getting decent responses from people. What are the driving conditions when it happens (what kind of terrain, only when turning or all of the time, only when you are on the gas or all of the time, in every gear or not, where does it sound like its coming from, etc).

The 4 wheel drives mostly when on the gas, and it happens all the time, although more often when turning. It happens in every gear ive tried, alteast the low ones in 4high, and all gears in 4low. It happens in the mud, or if I am simply driving through the woods with the 4x4 engaged taking a turn. It sounds like its coming from either the transfer case or the front end. I almost wonder if something is binding in the front end. I hope this helps clarify things

When's the last time you've checked out your CV Joints?

You might want to check your hubs also. When I had IFS mine made a nasty popping noise from time to time.

I think im just going to live with the noise until something lets go. The noise seems to happen most frequently when the 4x4 is under a load, such as going uip hills or through mud

I had this problem, and it was my factory auto locking hubs. If you have those, ditch them for some nice Aisin manuals.

Also, it very well could be your CV Joints..check your boots for tears, which could let contaminants into your CV axles which = death.
