Investigated back drums and found the problems. I have Superior axles in the D35 which are stronger than the originals. For some reason, the wheel studs had backed themselves out. Some were hitting the ABS sensor causing it to bend. The bent sensor was touching the tone ring and causing a ticking noise in reverse. OK, so used red thread locker on all 10 studs and tightened them back up. Straightened and tightened up the ABS sensors. While i was there, i greased up the drive shaft. Took it for a test drive and all running quiet.
Next on the list was to relocate the track bar which was a 5 minute job, and then centre the steering. Another test drive and all good.
I then removed the 4 HID lights off the roof. I am putting a light bar on the bull bar.
I told the Dept of Transport that i wanted to put a winch behind the bull bar and in their reply, they want a consulting engineer to address that the bull bar construction complies with CI-112C. Its the factory Jeep supplied bull bar so i cant envision any problems but they do tend to waffle on a bit.
OK, i have to put this project to bed for a few weeks, but in the meantime i am going to order a yellow box V5 speedo recalibrator to get the speedo accuracy to -0 +10% as according to the ADR's. I cannot get a speedo gear for the combination of tyres and diff ratio's i have.
I will also order the LED ADR approved lights for the tyre carrier.
The old girl is getting closer to full compliance.....

Not really related to VSB14, but just some stuff i thought i would add.
Had a mobile aircon guy come around today to service the Grand Cherokee. All good and now icy cold, but he said the compressor was a little worn.
While he was there, i thought i would get him to look at the XJ thinking i would have all sorts of problems. This is what he did:

Inspect 2 x Jeep

Evacuate and pressure test

Insert Oil, dye and full gas

Inspect for leak

Replace valve core.

At first, he said the compressor was just about knackered as it was reading 45 on his gauge and he said anything over 40 was getting tired and would not cool a car at idle. Anyway, he said he would add 30ml of compressor oil and gas it right up and it may come good. It did! The gauge started reading 25 which he said was like a brand new system. Said it was cooling better than the GC.
Total price was $300 for both cars fully serviced and running icy cold.
If your in Perth, then give Mac a call. Great friendly service and he comes to you which saves a heap of hassle.

Received the LED Autolights in the post and set about installing them. I thought they were Australian made, as they are $100, but opening the packet, they are made in Taiwan. I rang LED Autolights as i thought i may have some fakes. They confirmed that they have a Taiwanese factory... Anyway, the lights came with no mounting hardware and only a few hundred mill of wire. Of to the shops to get some trailer wire and stainless hardware, as well as a good 6mm hardened drill bit to get through the thick steel tyre carrier. Installation went well and fitted up good. I wired the lights up splicing into the trailer plug wiring and soldering and heat shrinking all the joints. All lights working well, and as you can see from the pic below, lights are visible from a 45 degree angle (original lights are blocked by tyre), so this should now be legal.

The Yellow Box speedo recalibrator arrived the other day. I read the instructions on how to calibrate it after a bottle of wine and it made no sense at all. The next day i re-read it and it all came together. You can get one of these from http://yellr.com/ . I got the plug n play version so i dont have to worry about splicing wires. Their customer service is great and the product looks high quality. The reason i need one of these is because according to Go-Jeep, with my 4.88 diffs and 29 inch tyres, i would need a 47 or 48 tooth speedo gear... which they dont make. So this calibrator solves the problem and i can change tyre sizes any time and simply recalibrate.
I will fit the yellow box up next week and do a write up, but i thought i would write up on how the yellow box v5 is calibrated. Firstly you need to work out how much your current set up throws the speedo out. Do this by [new diff ratio/old ratio]x[old tyre diameter/new diameter]. My calculator said 1.3460 which is 134.60% which is 34.60% fast.
You then hold down the two buttons on the yellow box (pic below), for 5 seconds to go into adjustment mode. There is a + and - button. For each second you hold down the + button, you adjust forward 1%. So i needed to hold down the + button for 34 seconds. You tap the + button to get thet smaller 0.6 increments. So i tap the + button six times. Then you wait a few seconds for it to go into memory and then turn it off to store the data.
After that, use a gps, road markers, etc.. to check it and make small corrections as necessary.

Sweet!
I have a Jaycar unit I use on my Sportage that wires into the back of the speedo. On the Jeep I tried putting it between the speed sensor unit and the ECU. It picked up the signal but couldn't calibrate it. Stayed on 40km/h. Ended up going with a new speedo gear cog.

The gearing is not the best as it was designed to go with my 35" tyres. According to Go Jeep, this gave me "RPM's at 65 MPH/105 KPH w/ 4.88:1 axle gears running 35's: 2,284 RPM". Now i have something around "RPM's at 65 MPH/105 KPH w/ 4.88:1 axle gears running 28's: 2,855 RPM", so i could do wheelies of the lights. Standard is "RPM's at 65 MPH/105 KPH w/ 3.55:1 axle gears running 28's: 2,076 RPM". I think the sweet spot with XJ's is around 2400rpm with large tyres and extra weight http://go.jeep-xj.info/HowtoSpeedoGears.htm . This setup is only to pass inspection... down the track i am looking at some Deegan or KM2 33" tyres which should give me RPM's at 65 MPH/105 KPH w/ 4.88:1 axle gears running 33's: 2,422 RPM.

I was thinking the Jaycar unit as well Werd, but saw this one and i thought it was pretty good and their customer service is great. I emailed them this Saturday afternoon about cutting the wiring loom down and got a reply within an hour!!
Anyway, i checked out the XJ for a location for wiring and the yellow box. The gear plugs under the car are right next to the handbrake. The handbrake sits in a large plastic dish that is perfect to drill and poke some wires through and then seal up with some silastic. I will route the cable up from underneath and then into the centre console. The centre console will be a great place to make adjustments from, and it will be hidden under the lift up arm rest door.

In my experience the sweet spot is close to a stock limited so 225/70/15 on the 3.55's or 225/75/15's on 3.73's, slightly higher rpm's at 100 then a sport, better performance and better economy...

Had a go at installing the yellow box speedo re-calibrator. It was a bit of hit and miss. Made a bracket and installed the box inside the centre console and that bit worked out well. I have made a hole down through the console directly above the handbrake and drilled through the plastic grommet under the handbrake to run the cable. The transmission plugs are only 20-30cm away. The miss part was that the supplied plug n play plugs did not fit. I have emailed them and either they can send me a new harness, or i will splice into the existing one.
According to the net, the speedo wires are as follows..
Wire 1 =
power
(constant +12 volt, or +5 volt) Orange wire.....
Wire 2 =
ground
(main vehicle earth) Black/light blue wire....
Wire 3 =
speed signal wire
(measures 0 volts then
12 volts (or 5 volts) as the wheel is rotated) square wave. Orange/white wire.....
I can run a multi meter on them tomorrow. Next step is to put console back in Jeep and tidy it all up...
