1993 Patrol y260 wagon when 4x4 is activated turning problem

[sarngon]

Hi guys, I have a 1993 Patrol III y260 wagon type and when I active 4x4 H, car struggle to turn right or left and make clinking noise like stripping something. I read some articles and someone sait that all okey. But I need to know it is normal or my transfer case, cv joint or diff. is broken :jawdrop:?

Thank you.

Hi mate, I am assuming you are running this test on a dort road?? If on bitumen then your asking for trouble.

I would recommend jacking the front diff off thengroun and put it on stands and try steering lock to lock. You could put it in 4 stands and spin the wheels. Spinning the wheels by hand should provide you enough feedback to figure if you have a smashed CV.

Did it start to do that all of a sudden or has it always been like that?
Does it do it in 4x4L as well?
Did it first happen when doing some 4X work?

Your symptoms are exactly like how a Mechanical Diff Lock works (Detroit Locker, Lokka etc)

As suggested... If you jack the front diff so both wheels are off the ground, engage the hubs and turn the wheels by hand that will help pinpoint the issue.

Maybe the chain in the transfer case has stretched/worn and is jumping teeth under load. I have seen this happen twice on friends vehicles with alot of kms. One was able to find a replacement chain and fix it, the other sold his vehicle.
