Hi, I've got a 95 XJ 4.0 HO. The other day it started making a slight grinding noise near what at first seemed to be the front end, but then also sounded like it could be coming from the t-case area.
It does it at very low speeds, 10mph and less. It happens both slowing down and taking off, but once it's up to speed I don't hear it anymore. I do notice it more if I'm taking off on a slight incline, but once again disappears as soon as I get up to speed.
At first it sounded like something on the wheels like bearings or brakes, so I changed the brakes and still there. Maybe the t-case or something else? I'm not sure, its got me stumped! Anyone have any idea what could be causing it? Any help would be great. Thanks guys.

 

I'm not sure but any chance the hub bearings could be worn out?

 

That could be, I've never checked them.
What's the best way to do that?

 

2000 but i just had the motor rebuilt, new head, new lifters and new camshaft. also there is a new water pump, new hoses, new fan clutch, new thermostat and radiator.

 

im not really over thinking nz road legality is an*l most cars on usa roads wouldnt pass the nz road legality test. to them a free hanging diff is a sharp edge. yes i do realise that its only matters to felled pedestrians and insects but removing the front diff is a LOT more weight than just dropping a drive shaft. to me having 2wd is a boon as i wont be lugging around a front diff i never really use. see my point?

 

Yup, sounds like heatsoak. It has nothing do with with any maintenance you have done, or the condition of the parts. Theres not much you can really do about it, Its just because of the design of the motor. The fuel injectors get so hot that the fuel that sits inside them boils (when the car isn't running) so they end up misfiring when you go to use them again. After a while, theres enough new fuel that it will run properly. Jeep's fix was wrapping the injectors in a type of insulation to keep them cooler.

 

Will a 99-04 WJ tie rod fit on a 00 XJ? I know its supposed to be a ZJ tie rod but I came across a new WJ one for $60 and was wondering if it would work or not

 

So quick question (maybe not)....I'm trying to figure out what mopar oil filters besides the MO-090 cross references the Motorcraft FL1-A. The mopar is the same thread pitch but a shorter filter. I tried searching for a bit but no results.

 

I don't think so, but I may be wrong

 

if i put an electric fan in my xj will this help keep them cooler and prevent this from happening?

 

Hardly. You might try laying some sort of heat deflecting material like woven fiberglass under the injectors, or get some hood vents, they reduce under hood temps by allowing more airflow throughout.

 

I don't think there is one that fits the bill you're looking for.

1085 or 1515 Napa.

 

Hood vents will help

Hood vents are awesome.
