not to well up on wrangler clutches so some help please , karl the guy with me at silverdale with the black yj 4.0 cant get his motor into gear it just grinds and when its i n neutral and engine running its got a rattle but it goes when he puts the clutch pedal down , the fluid is ok and it has no leaks , is it a thrust bearing issue or is there a more common fault ?? your help please ....kev.....

sounds like a release bearing collapsing or on its final legs, in the worst case it could have damaged the diaphram on the clutch pressure plate so not releasing fully. I know it happens on tj's but not heard of it happening on yj's but you never know.

That sounds like the release bearing.

Had same with mine - within 20 miles it chewed the clutch - so DONOT drive it - or else it will be the full clutch.

There is one listed on ebay - but don't know if his is the hydraulic combined one :-?

either way dont drive it and take the gear box out.

if it is the thrust bearing might be worth while swapping the clutch etc as well while your at it

there is a slight chance you have the internal one easy to tell if you cant see an axternal slave you have the dearer internal bastard

mad wolfie · « **Reply #7 on:** April 27, 2009, 05:14:52 PM »

right its the dear internal one and we changed it and its still the same has any one got a good clutch for a 1994 4.0 wrangler so we can make sure its not gearbox issues..or has any one else got any other ideas what we should do ........kev.......

Before you pull it apart again......

I had a problem when I changed mine. Brand new clutch and hydraulic slave, bled ok but not releasing properly. The clutch master cylinder piston may only be half way up the cylinder. Try pushing the pedal to the floor and then let it flick up sharply as if your foot has slipped off the pedal. Do this several times to work the piston back to the top of the cylinder. Worked for me.

it still has quite a bad feel , like vibrating until you push the clutch pedal in and it makes a noise when driving but it doesnt grind when trying to put it into gear any more , are the 4.0 yj's and and the Cherokees the same clutch and gearbox ?

Mike Pavelin · « **Reply #10 on:** April 27, 2009, 07:56:33 PM »

Yes and no. The 4.0 Cherokee was never available in the UK with manual (Mine's a US import). The 2.5 diesel Cherokee uses the same AX15 gearbox but the clutch is different.

can i convert it to auto easy and what donor motor would i need....

Mike Pavelin · « **Reply #12 on:** April 27, 2009, 09:08:22 PM »

Not worth the hassle.

mad wolfie · « **Reply #13 on:** April 27, 2009, 09:16:44 PM »

so i need a 2.5 diesel then for the box

?

Mike Pavelin · « **Reply #14 on:** April 28, 2009, 07:43:01 AM »

Unless you can find another YJ or a TJ. You'll need to keep the bellhousing off your old one as only early YJs had the same hydraulic release bearing in the UK.

mad wolfie · « **Reply #15 on:** April 28, 2009, 04:51:56 PM »

i have spoke to my mate karl and he wants to go auto . what problems are we going to come across and will a 4.0 auto Cherokee be a good dona motor

Mike Pavelin · « **Reply #16 on:** April 28, 2009, 05:17:51 PM »

You could fit the AW4 from a Cherokee but it has electronic control so you will need the AW4 control module, possibly the engine control module for the same car, which needs to be a '93 or '94 to work with the existing sensors on your YJ, the wiring harness from the XJ and someone who knows what they're doing to splice all the electrics together properly. You'll also need custom propshafts as the transmission will be longer. The easiest option is to find an automatic YJ or TJ with the old 32RH transmission as this has no electronics.

i'll have an aw4 kicking about soon, infact i may be breaking a complete 95/96 cherry

mad wolfie · « **Reply #18 on:** May 03, 2009, 06:26:10 PM »

because of we dont know if its the clutch or gearbox thats faulty and cant afford to fit a new clutch and then find out its the gearbox , this is why we thought a donor motor eg mot fail thats got a good motor,clutch and tranny would be the best option , what would be the easiest and cheapest way to fix it ? would the 2.5 Cherokee tranny and clutch go straight on a 4.0 if thats all we can get hold of ....

Mike Pavelin · « **Reply #19 on:** May 03, 2009, 06:57:59 PM »

No, the 2.5 petrol has an AX5 which is smaller and isn't tough enough for a 4.0. By the way, did you check the pilot bearing.

mad wolfie · « **Reply #20 on:** May 03, 2009, 06:58:58 PM »

so we need a 4.0 manual then ...

Mike Pavelin · « **Reply #21 on:** May 03, 2009, 07:27:10 PM »

The AX15 gearbox from an 95-99 2.5 TD will do but you would need your original bellhousing to accomodate your hydraulic release bearing and the diesel clutch is wrong. Also the clutch for a 4.0 with a conventional release bearing is different so only the clutch for the correct year YJ will do.

Bubba · « **Reply #22 on:** May 03, 2009, 08:27:38 PM »

im breaking a 2.5 yj if it helps

Mike Pavelin · « **Reply #23 on:** May 03, 2009, 09:54:22 PM »

That's an AX5 as well.
