    4.0l XJ starting problem

    I have done the check and there definitely seems to be a loss of pressure as it fires up quickly when doing the key thing. I will be borrowing a pressure gauge from a friend this week. What I need to know is how to pinpoint the leak as there seem to be two possible places. One is the pump check...

    Swing out wheel carrier XJ.

    I have a swing out spare wheel carrier on my 4.0lit XJ. I believe these were a factory option for a short time. Has anybody any documentary evidence that these were original fitments? I am looking for a picture from a manual or brochure that clearly shows this so I can prove that it is original...

    4.0l XJ starting problem

    Something has changed. I have two 4lit XJs and until recently they both started with the first flick of the key, winter or summer. Now one of them, the 1994 one, needs a lot more cranking than it used to, but it always starts. I have checked the usual things like plugs and distributor cap which...

    1994 XJ 4.0l lambda sensor mystery

    I have upset something. after fruitless attempts to get the sensor out of the cat I resorted to WD 40 and then my old faithful penetrating oil, diesel, which I have used for years on seized components. Today the engine cut out dead on a roundabout. It restarted OK seconds later. Driving back...

    1994 XJ 4.0l lambda sensor mystery

    I have not tried this yet as it means removing panels etc. I have the dreaded Test coming up on 21st for re-plating the car from UK plates to Spanish. Everything sees to be working OK at the moment so I'll have a look after the test is done. I will also get an idea of the exhaust pipe emissions...

    I have been given the following Jeep part number 52079197 which comes up as a temperature sensor for a RHD European spec on a Mopar site but I cannot see any further details. Rear O2 sensors did not appear till later. Comparing the pic above to what I have shows a much fatter item, mine only...

    1994 XJ 4.0l lambda sensor mystery

    I have been advised that this is not an oxygen sensor but a temperature sensor. The mystery is why it is fitted to my Jeep when after cat oxygen sensors did not come in till 1998. I can find no mention of temp sensors. I don't know its purpose. Is it simply to warn of high exhaust temps or does...

    Cherokee 1994 XJ Front Axle question

    I have swopped over the RHS tyres and the problem seems to have gone away. I have not done a long run yet, but locally on smooth roads things seem to be quieter. I will jack up the back end and check for runout on the rim and tyre. It is possible that a large local pothole and believe me there...

    Cherokee 1994 XJ Front Axle question

    Thanks for the info. I think mine must have the flush seal. I was just surprised that there is no bearing at this point. I am still looking for what is making the noise. I intend to swop some wheels around to see what happens.

    Cherokee 1994 XJ Front Axle question

    I have just changed the front RH hub bearing in my hunt for a noise up front somewhere but it has not cured the problem. It is speed related and in time with the wheel revolving. I began to think it was the bearing the end of the axle tube behind the UJ but having looked at some pictures on the...
