WJ grand cherokee 4.0 2004. Any good?

[scrwright]

haven't filled mine for years thanks to the LPG, but £50 of LPG gets me 250+ miles & £20 of petrol barely gets the tank wet LOL

[tr7v8]

Juts had a service done on mine by my trusty indie. Full 120K service, includes all fluids except gearbox, fix the dodgy rear light which eats bulb fast than I eat food. Rear discs & pads & clean & lube the handbrake mech for the MOT. All in £495! The rear light needs replacement as it was full of water, but no obvious crack. New one on fleabay is £35. Newly bled brakes mean the pedal is much firmer.

Even if you have to put £500 into it to get every job done up to a decent standard, you should have a solid workhorse that will last many years to come.
These WJ's are kinda the last of the "old Skool" off roaders/sport utility vehicles, live axle's and big engines !
Get yourself over to http://www.wjjeeps.com/index.htm and register on the forums. Ive got loads of tech help there. There are a few UK users online.
This guy http://www.4playjeep.com/ for UK parts and endless chat on the phone, he's really helpful.

I meant to ask you before. I thnk I'm being a bit thick but where do I register on the wj jeeps forum? I've looked all over the link and can't see any forum.

Cheers.

I could be wrong, but I believe it's just an information site rather than a forum.

[Spare tyre]

i went out greenlaning with one yesterday, really good, its has a 2 inch lift on it, but road tyres, seemed good with road tyres

All terrains are being fitted on it today

[Pesty]

Excellent.

Ill be looking into that. Drove mine up and down a really steep grass bank twice as tall as he car. Car just did it so easy didnt look that impressive.



I have a problem though. Car is stuck in first gear. From reasearch it seems irs a common fault. Could be varios speed sensors or. Solenoid in he gearbox. As i have atf4 niw and was going to do it anyway ill try that solenoid.

[scrwright]

do the speed sensor first (or read off the fault codes to confirm) if it stays in 1st to the red line then changes up it is the speed sensor. Only 1 on a 4litre, cost around £40 and takes 10 minutes to swap

[Pesty]

Stays in first right up to red line and still won't change up,

Which speed sensor?

My code reader died so I've ordered another should arrive any day.

If you scroll down the link page I posted you'll see a blue box called "jeep garage.org"

Thats the linked forum for the WJJeeps info site

[Pesty]

Done thanks

First page there is somebody talking about changing that solenoid.

Might just order this anyway and change it as a precaution. Sounds like it might go anyway. Easy job by the looks of it.

Or get the other sensor

Will wait for codes

[MatrixXXx]

you need to make sure the tyres are the same size and wear as different circumferences can cause wear in your transfer case, also make sure you use the right fluids as there are a few different types depending on your type of 4wd. ie quadradrive or select drive.
i bought 2001 4.7 and love driving it, just wish it had snowed this year to try out the 4WD, i do fancy green laneing some time , although they do recommend you go in a group , so you can tow each other out if you get stuck. so if any one in Yorkshire fancy's a day out !

[Pesty]

Yes tires being sorted.

Will be changing the fluids after I've sorted this gear issue. The only reason I havnt ordered any yet is I'm not sure what diffs it have and whether they need the friction modifiers etc etc,

But first things first I need it out if first gear

[scrwright]

look on the tabs on the diffs, they have the oil spec stamped into them. will either say 80w90 or 75w140, also next to the gear shifter look at the badge, QuadraTRAC is 80w90, QuadraDRIVE is 75w140. All UK WG Grands got the 247 transfer case so its the slippy oil you need NOT AFT.

Code in mil was p0720 which is output speed sensor.

Just swapped it out changing gear like a dream. Really smooth. Cost £17

I'm a happy chap again. Although my drive is covered in oil

Not sure oil should have come out if there it was really over filled.

Oil is also very light coloured. I'm sure the atf4 I've irdered is red hmmm.

[scrwright]

yhep, oil comes out when you change them. Should be atf 4+ which is red. Put your box dipstick on a white paper towel to see the colour better

[Pesty]

Well that's my problem I over think things.

I was going to get my oil drain bowl and some cardboard but looked at it fir a while and thought it's way up there all the oil will be in the pan lol. Would have meant be getting up again and I had the spanner in my hand


Anyway easy job car running like a dream again.

Just given the jeep a long run from deepest somerset to brands hatch via crawley.

Filled up at taunton just by motorway and got up there and back to the service on a303 next to boscombe down before the trip computer got down to 50 miles left and i filled up again.

So 338 miles, 24.9 mpg, getting stuck in traffic out of brands killed my mileage i think with a clear run out i may of got back to yeovil on 1 tank if i stuck to 55-60 mph?

[Pesty]

Now the front brakes are done I dare use it for why I bought it.

Didn't even know all that was in there. I'm still averaging 18 mpg but I know the calipers were seized. Inside pads were to the metal outside pads like new.
New disks and pads fitted floating pins lubed so wel will see if mpg improves.
