Awful Clonking when in 4x4 part time

Hi,

I have a 1997 Jeep Cherokee Limited with 81,000 miles on the clock and is in very good condition.

However recently we have just discovered that when you put it into 4 wheel drive and then accelerate there is an awful clonking noise. As if gears aren't engaging.

I know the bare basics of mechanics, however if you can try and keep things simple that'll be great .

I have posted a video which shows the problem.


Thanks

The shifter is connected to the transfercase via linkage, mechanical metal rods.
This linkage sometimes needs to be adjusted. If you use the search box up there ^^^ and use keywords like "xj, transfercase, adjust linkage etc etc" you will get many results on how to adjust, detailed pictures and all.

How does it act in the other positions. Have you tried 4lo?

The chain inside is also known to stretch.

It's a good time to change the fluid. Remove the fill plug first, thn drain plug, inspect fluid for metal (very fine glimmery pieces are normal). Look inside the drain hole for a quick check of the chain it should look tight, not saggy.. Fill transfer case with fresh auto tranny fluid..

As suggested, adjust the shift mechanism, and then consider that the transfer case chain is stretched and needs replacement.
