Occasional grinding noise front right of 96 3.1..

[geeves]

From about 96 in the bighorn and 97 in the mu and wizard they introduced an electronically controlled diesel pump. That has the crank sensor. That engine has more power and drinks less fuel but has its own set of extra problems as it gets old. 96 was 26 years ago

Yeah mine is the 96 3.1 with electronic pump - but not the late 96 with TOD. I'll get my auto sparky to also do a code reading on it to try to confirm crank angle sensor.

Not alot of data on this sensor. Will try to narrow it down. Just asked Gavin out at Rangiora if he has any 2nd hand ones - get an idea of where it fits, what it looks like.

[geeves]

Not sure Gavin is doing that any more. Its a pity as he had a lot of stuff

[mudgrip4]

He's no longer trading as such, but happy to go check in his sheds if you need a bit and call.

Arse...alot less noise from front left now after upper balljoint replacement and brakes checked, but still a groink groink from time to time. I suppose this means that little CV support 'needle roller' bearing. Anyone have a pic, diagram or part number?

[geeves]

Pretty sure I got mine from https://www.sthislandbearings.co.nz/ from a listing they had Its in Kingsley street. Otherwise get the bearing out and it has a number on it. What is your cv to hub seal like? I got that from Autozone in Kaipoi

[mudgrip4]

Cool thanks - might have be extraction then head off to find new one. I will keep that seal in mind too.. Correction - noise is front right not front left.

This information is for a Mu put is probably the same as a Bighorn in this area.

Thanks for diagram Turnturn. Pilling it apart this saturday.

One question Geeves and others - am still getting 4wd green light remaining on. 96, Auto box, fixed hubs, non TOD model. Recently put exchange transfer case in and checked electrical connections - seem ok. Some suggest its a little vaccuum hose under the power steering pump? Can't think where/what that is - what has a vaccuum line there got to do with 4wd operation? However reconnection or repair to this hose seems to work for some people so will look for this also. Where precisely is this? Thanks Mike

[geeves]

The 4wd light is controlled by a switch on the diff. When you select 4wd a switch in the transfer case activates the 2 solenoids on the diff which allow vacuum to activate the clutch in the diff which activates the light switch. If the light is on the clutch in the diff is activated.
I had the opposite problem in my wizard but my answer was to rewire the solenoids so I could activate the diff separately to 4wd. It was meant to just test the electrics but I quickly realized how useful low range 2wd was when backing trailers so my temporary switch remained blue tacked to the dash for 4 years
My money is on a bad solinoid
