drivetrain

When accelerating, I hear a loud knock or pop noise coming from the drivetrain. I pulled the rear diff cover off and the ring & pinion looked good. Some of the spider gears looked pitted, but none broken, and no sign of metal shavings. I dropped the front driveshaft and the noise was still...

What the heck are these things? They're on the transfer case and rear axle on my '97 XLT, which rolls quietly, but not on my '99 Limited (4wd) which howls at speed. They're also not on my '98 Sport, but it's a 2wd. The guy I bought the Limited from replaced bearings and the transfer case trying...

I have a 97 Ford Explorer XLT 4.0 l V6 OHV it has 181k miles on it. When I drive Down the road at 55-65 MPH it has this like grinding/ whining noise. It recently started doing this. The parts have never been changed at least to my knowledge. The parts that I’ve changed myself were : Inner and...

Just got back from a 1500 mile drive- have noticed an issue I had before become markedly worse. It's humming sound- not a wheel bearing (too low pitched), definitely in the drivetrain as when I let the power off it stops (so is excited by torque through the drivetrain). It was peaking at 33...

Anyone know why I might have a roadspeed-dependent hum which sounds like the above? It seems to come from the front end but is worse with a (480lb) load in the back..

I was wondering if its possible to swap the 3.55 gears for 4.10 gears in my 2006 eb v8 4wd, ive been looking at gear kits and they all say they are for the mustangs, but they also say they fit independent . So im not sure if those will work, also i cant seem to find any for the front...

Been searching for a week now. Ebay, AutoZone, Advanced Auto Parts, O'Reilly's, Amazon, RockAuto,and just google in general. WHY is it so hard to find replacement CV axles? I'm looking for front ones specifically. Someone please correct me if I'm not on the right track. This started because of...

Hello All, I have a 16 Explorer with 36k on it. Since about 25k, I have been experiencing my transmission occasionally slamming into gear. When slowly accelerating from a red light/stop sign, mostly when shifting between 2nd and 3rd gear, engine will go from 2-3k rpm to about 5-6k rpm...

Hey yall. I have a 2008 ex with the truxxx 2.5 in lift amd running 255 75 17. I hit a guard rail last week and tore my ex up. Ive had to replace both control arms on the passenger side as well as the axle and rack and pinion. I finished it up today and on my first test drive i keep hearing a...

Does anyone know if the 14 Explorer Sport has a viscous coupler in the drivetrain or not? Tried searching online and have had no success.

Hello ExplorerForum, Been a frequent lurker for the past 5 years but never had any questions to ask until recently. My trucks been very well maintained over the course of it's *known* life. It's been smooth all the way up until the start of last year, transmission starting to slip, engine now...

Hi all, I have something quite strange happening, can't find any answers anywhere else. On only one of my tires (front passenger), there is a strange looking circular pattern (almost like a Spirograph), that appears around the outer edge of the sidewall where it meets the tread. This tire is...

So this has been a problem that's been going on for about a week now, had it to a shop to get the transmission fluid and filter changed, which definitely improved shifting, but did not resolve these clunks. This is on an automatic 2003 explorer xlt with the 5 speed. Here's what's happening...

Hi all, I recently took my 03' XLT Explorer AWD to a CJ Tires location. This location has always been good to me and I never found fault with anything they've done until today. Here's the run down of what they said is wrong: Both front wheel bearings bad Both sway bar end links bad...

Hello, I have a 2003 Mountaineer with a 4.6, AWD, 3rd row seating, towing package, and a remanufactured transmission. Aprox 164k miles. Original drivetrain components except the transmission. Has recieved diff and transfer case flushes ect same owner since 2004 (my Aunt) I have a very...

Hey everyone, I have a challenge for some of you... My explorer (1999 4.0L SOHC) recently started making a metallic rattling noise when driving/idling. I made a video in hopes that someone could recognize that noise, well I made a few in case the shorter version isn't clear enough. I hear it...

Hello again. Vehicle is 08 Explorer, 6 speed, 4wd. 68K. Started noticing a noise from front end which sounds like a bad bearing or knobby tires. Noise continues after: new front wheel bearings(replaced twice in 2K miles), new front half shafts, new tires, brakes, alignment. Car drives out very...

Help! Just had trans completely rebuilt. Got it back from the shop about 2 weeks ago. Was running pretty smooth at first, except there was *occasional* intermittent slight vibration at city driving speeds (25 to 50 mph). At first I thought slight vibration was probably caused by uneven...

The boot on my front driveshaft has a huge cut in it and I'm losing grease from the u-joint. The only way to fix this is to completely replace the front driveshaft. When I stopped by autozone to ask about it, they said there is a 23 in. one and a 24 in. one. Two questions: 1. How do you...

My 2004 Ford Explorer Flex Fuel 6 cyl full time 4wd (160,000 miles) has developed a vibration (rhythmic thump) when decelerating on a flat smooth road. It feels like when you drive over the spaces in concrete. No noise, just spaced vibrations. It seems to do this at speeds above about 30 mph...

Well, I've got an 97 sport with a 4.0 sohc awd. So this noise has happened say 3 times now in the last 2 weeks. My first thought was it sounded like a converter shutter kinda like runnin over the alert ridges on the side of the road(or whatever u wana call it. But tonight on the way home it...

I just bought a 97 explorer XL with th control trac.. I have a rotational clunk i can feel at idle and gets faster as i acelerate. So i removed the rear shaft and the feeling went away? any help would be appreciated.. im a single dad a need this vehicle badly.. ujoints "seem" ok but im at a...

I have a 93x eb and i just fixed my 4x4 switch motor went 4wheeling, with stock tires and got hung up on the front pumpkin (figures i need a body lift and 33's), i knew i was grinding on the housing. After that i went down there to check for any leaks and it was leaking gear oil out of the front...

Guys and Gals, I have been living with a vibration for some time. It was getting worst. Would feel the vibration on the floor (not on the steering wheel) starting around 50KM (30mph) and would become loud. Would still vibrate if placed in neutral regardless of RPM. Assumed it was coming from...

Hey guys, This actually isn't a new problem, but a problem that I've had since my purchase of this 06' EB V8 in December, however it's progressivley gotten worse. It's still under warranty (factory until October 09, and then CPO thereafter) however I have taken it in for this problem already...
