About Differentials... Non-Fox Related....
Hi All.
So long the last time i have posted here. But i check the forum every now and then, so mny new people here. It is good to know about more people interested in our now 30 old cars. Still have mine, but it is not roadworthy, i have fired last year and well...got a small fire because the improper adjustment of the carburetor literally "exploded" and fill of fuel all the engine bay. No problem, the car still lives.
Well, i am driving currently an old Jeep Grand Cherokee 94 with full time 4wd . I work for the fire department where i live, so i needed a "reliable" (i missed this point...) car to drive between sand,water, mud, an what not. Got this truck borrowed from a friend, and the only mod i did was to put 31*10.5 R15 tires. Worked real good for some time.
6 days ago i was driving normal and feel a "thump" at the front. I stopped at the next block and checked the front suspension, and all looked normal. Running two more blocks and feel a constant clunking noise, so i headed right to home (thankfully i was near from it...) and checked again.
Like i said before , the truck has de 4.0 liter inline six with the quadratrack 1; for those who dont know, jeep says that there are like 50% torque between front and rear wheels all the time, so its a "true 4wd" ,and yes, gas economy is abismal, like 8 mpg at town.
Well, back to the main idea, checked underside the truck, put in park , and no noise is produced. Put in "D" with the parking brake locked, and the front driveshaft turns, but the front diff doesnt, and the clunk is produced like 1 per second, varying with the car speed, so i think the front diff is toasted. I did an small test, mashed the gas pedal quickly and yes, no front wheel drive action.
At this point i think i will need to rebuild the front differential. I have never done a differential rebuilt. But now i have lots and lots of tools, because i still always works on cars.
i Have done lots of research, and some people says that is not a easy job. But i have been reading that an important part of the differential rebuild are the adjustments; backlash and bearing preload. I need a micrometer for the backlash, and a torque-meter (i have one) for the bearing preload. Apart from that, what else adjustment is critical for the rebuild. Im still researching and checking books and youtube which bring some light to this matter, but i want to know if somebody did some of this work before.
Thanks in advance, and sorry for the typo, never learnt enough english....
