Disassembly of 1998 Ford Ranger 8.8" Rear Differential. Replacement of rear bearings was required including pinion and carrier bearings. This is an overview of the process. Some steps may not be shown or shown in part. Refer to a shop manual for detailed instructions. I am not a mechanic but I do have a lot of experience with vehicle mechanical work and have had substantial coaching from my brother who is a mechanic.
You may wish to view my related video on axle bearing and seal replacement.
I have a question, my 02 ford ranger started making a whirring noise in the rear. Then after maybe two weeks the noise got worse. A loud clicking noise that reminds me of the sound a bicycle tire makes when a playing card was pinned on with a clothes pin. And it's getting worse.
Any ideas? This is my only means of transport
all you needed to do is adjust your shims in the pinion gear and tighten up that play... the bearings had wear, but would still last another 100,000 miles no problem
Infinity QX4 '99, making a vibration like noise when rpm 2000-3000 20-35mph, the noise is similar to heat shields vibration but it is comming from rear defferential. Almost like an oscillation. Wat can it be does anyone know? (as of now winter it doesnt do it, but def doing it in summer) Mechanics are baffled...
Ok, question for the professionals: 2003 ford crownvic lx. new axles and axle bearings. but still 4 more bearings right? one of them sounds rough, more so during braking but rough all the time. when it shifts to 2nd i feel a slight bump somewhere, thought it was the trans but idk. is somethng misbehaving in the diff?
Did any one notice that very little fluid came out when he pulled the rear cover?
No wonder it has a problem. Change the fluid at 60,000 and use Synthetic 75w-90 if is a locking rear make sure the gear lube has the limited slip Additive in it or buy it to add.
(Friction Stabilizer) it will say on the bottle. With Synthetic you are good for another 100,000 miles or more.
NO. Eaton G80 is the norm on most GM products for the last 25 years. They are locking diffs, but do NOT have clutch assemblies. They require only regular gear oil.
nice video. I am in process of doing my rear end right now. this is my first rebuild. watched many many videos on you tube, read many articles, and even ordered a book from amazon on how to rebuild the 8.8" ford differential. anyway just wanted to say the gear oil that came from your differential looked like tar instead of gear oil. not picking on you by any means. but this was a good video to see how to remove the old bearing cups. will be posting a few of my own as I work on mine.
FINALLY!!! a video on youtube where the guy knows what he is doing.You explained the exquisitely ....all is understood. oh and the same applies for the 01 mustang .Thanx good job.
question, would replacing the rear bearing in my 99 Durango solve this issue? i am hearing a loud whine sound(like a turbo spooling up) when i reach the speed of 30mph and above. this began after pulling a loaded u-haul trailer a month ago.
Afetr I removed my driveshaft I found no fore/aft, up/down, or side/side movement in my pinion shaft. I deduced that the bearings were probably in good condition. I found no chipped gear teeth on my ring and pinion either. My diff gears were shiny and had a lot of play between them. After I replaced the diff gears about 70% of my rotational play went away.
awww... you didn't show the part on how to take the axles out. I'm planning on changing the axle bearings and seals only. Is there any way that you can further describe how to remove the cross pin and bolt? Is this easy to do on the driveway or would it be faster on a lift?
I had a 98 ford ranger 4x4. Bought it new back in the day. Worst truck I ever owned! Nothing but problems from day 1. In fact now that I think about it all my Ford products were junk.
What were the symptoms on the truck before you did that job? was it Vibration at high speeds?? My 2001 ford ranger vibrates from the rear end at high speeds and I can not figure out what is wrong, I had the tires balanced but no, I think it feels like loose drive shaft or something in the differential. any advice??
my differential gears dont want to come out i took out the 2 holders then the pinion yolk and i try to pull it out could it be different on a 96 ford ranger 2wd
