I know there must be one somewhere, but where exactly on a 92 3.1L Bighorn? I have read the comments about it being difficult but still can't spot it. I've even got a 3 legged remover ready to do the job.

Many Thanks
Dave

I hate to admit it but Im one of those who find it difficult,I can undcrew the filter no problem, its squeezing the used [ and the new ] filter between the propshaft and suspension [ I think thats what it is ] arm I find difficult obviously Im doing somthing wrong

Thanks very much. I had been looking in the engine bay, as that seemed logical. The suspension bit is a torsion bar that actually does the springgy bit by being twisted. As previously used on Beetles (proper ones) and moggy 1000's, to name but 2.

Thanks for your comments,I suppose I deserved it! it is a torsion bar, you can tell I know a lot about motors! It dosnt stop me thinking that the trooper is one the best towing vechile Ive ever come across I just need to learn how squeeze the oil filter between the front propshaft and the torsion
bar

cheers Bryan

I'm sorry, but I really don't see what the problem is?
I use a strap wrench on my 1/2" extension bar, then once undone,
I take take filter far back until it drops out, how hard is that?

The filter on these early 3.1s is quite a fat one & is a tight squeeze as you've found out. There is some variation in diameters between different manufacturers of aftermarket filters & 5mm difference in diameter would make the job easier.
Does anyone have the make & model number of a filter that fits easily thru the available space ?
From about my vintage on some of these came with a more expensive but longer & narrower filter which makes it much easier.
I put mine up on blocks to give me some clearence underneath, & go in from behind the right front wheel. I use a three arm filter wrench on a long extension as Dave has said, pack some rags in on top of the cross member to soak up any spilt oil, punch a hole in the lowest part of the filter with a screw driver to let some oil drain, undo it a turn to let the air in to drain some more, then when it has largely drained unscrew it quickly, slide it back toward the rear of the torsion bar where there is some more clearance & away I go. Easy after that.
HTH, Cheers, Steve

Hello Shinz
The best way as you say is to approach the filter from the gear box end of the engine with the car either on jacks or ramps ... I prefer a jack as its amazing how much more comes out due to the drain plug being on the side of the sump and lifting via the front axle diff cocks it to that side......... prior to loosening off I get a piece of cardboard bend it to 'V' shape and make sure its long enough to slide under the full length of the filter cannister up to the housing and then using a strap type constrictor that fits on a socket set extension bar release the cannister ....... the oil flows down the cardboard straight in to your waste oil container......no oil accumulates on the cross member to drip long after the filter change and the cardboard also aids an almost direct route out for the filter.
