uh, k then. i have a question. why hasnt my o2 light turned on? rubbing 240xxxmi and nothing.

 

Did you check under the dash? There is a clear box with gears in it. If that isn't there then the po removed it. There are 5 reasons the light won't trip I can think of. 1 you don't have a timer any more. 2 the cable was removed from the box. 3 the bulb burned out. 4 the wire was cut to the box. 5 you have other electrical problems on this circuit. The light will not trip if the o2 sensor goes bad actually you will not get any light when any sensor on a renix goes bad. These are pre obd vehicles i.e. you can't scan them with a scan tool, you can't buy one and Jeep doesn't have them, it is called DRB II. No one has this system anymore. If you know you have put 80k+ miles on the vehicle it is recommended you change the o2 sensor per the owners manual. Actually it is more like 82750 but 80k is a safe estimate.

 

okie dokies then. i'll check it morrow if it aint raining. would you also know why the rear wiper dont work? stript it down and all that jazz. jiggled the motor and the wiper moved too, as if it was seized up. also, the PO told me the ABS is goin out. k then, is the ABS a big black saucer thing thats mounted behind the brake thing? if so, i aint got it.

 

How do i add a spacer or buy a spacer what doe it consist of because i dont wanna trim or damage a good lookin xj

 

the rear wiper motor could be bound up or again a bad electrical connection somewhere, I wouldn't bother looking at the fuse as it moved. if you jiggled it and it moved then it is probably binding somewhere or it has a bad electrical connection in the wiper motor.

the big black saucer thing you are talking about I am guessing is your Brake Booster, it should have a hose going to the intake manifold, it is powered by vacuum which is why there is a hose. if you do not have the booster then you shouldn't have brakes at all as it sits between the brake pedel and the Brake Master Cylinder (the thing that has the brake fluid in it). if the ABS is not working well you may need new wheel sensors. the sensors read a tone ring usually on the actual axle shaft, sometimes on the break rotor, as the shaft turns the sensor reads the hi and low points on the tone ring, which it measures the speed of the wheel. when the wheels are not matched up when brake is applied i.e. one stops turning, both front stop turning and the rears are, the ABS system will kick on allowing the brakes to pulse so they do not lock up. this allows you to still have control of the vehicle while applying the most amount of breaking force. if you lock up the front wheels you will not be able to turn, so with ABS you can still control the vehicle. I don't know where the sensors are actually located on the XJ as I don't have ABS, I also have not looked into what the ABS system is made up of (the different parts).

 

A wheel spacer is usually a solid piece of aluminum with holes and studs in it, that match your wheel and hub bolt patern. the XJ has a 5 x 4.5 bolt patern that means 5 bolt by 4.5 inch spacing. the spacer you are looking for will be something like 5x4.5 to 5x4.5 1.25" this translates as your bolt patern at the hub to your bolt patern on the wheel and the spacer is 1.25" thick (pushes your wheels out by that much). there are companies out there that make them. I got a set off of ebay, however you run a risk with quality and fitment being correct with them from ebay. Spidertrax sells them also you can check them out to see what they look like http://www.spidertrax.com/1987-06-Wr...category=10000

 

How many will i need 2 make the tires wrk without rubbin

 

you need a total of 4 spacers one for each wheel

 

Will it flex after i put the spacers on Im tryin 2 do the 31x10.50R15 for my 1990 xj will i have a problem

Not much with 31's it is usually recommended to have a 3" lift for 31's. 235's are about the biggest you would want to go if your wheeling it with no lift. That size tire will still fit in the well when the suspension compresses. Also with 235's you would not need spacers or different wheels to change the back spacing.

 

What are 235s

 

I like the 235s on my jeep. It is basically a 29 inch tire, mostly just a bit wider than stock, but nice. 235/75/r15

 

I c now is it the same size as 31x10.50r15 or can u tell a diff

 

Do u have a pic i can c of the tire on ur jeep please
