Vibration in my steering wheel, and gas pedal when accelerating

I noticed after getting up in speeds of about 100 mph last week that now every time I accelerate I have a vibration coming through my steering wheel, and gas pedal. The vibration starts around 30/35 mph and gets slightly worse until about 60 mph. The vibration is not so bad that the vehicle can't be drove, but it's not normal. I have had the wheels, and tires looked at, and everything was fine with that. Also a front end shop lifted it up, and told me my front differential, and left axle is bad, and needs replacing. I can believe the left axle part, but as far as in the front diff being bad, I doubt it. That's just a guess coming from the mechanics! I have no symptoms of a bad front diff as far as I know, from looking it up. The vibrations stop when I'm at a constant speed, and no vibrations at all when I step on the brake! Vibrations are the only thing I feel, no noises at this time. What could be the cause? I know an unbalanced drive shaft, motor mounts, CV joints, axle, & U-Joints could all be a possible culprit, but none of this was mentioned by the shop.

2000 Ford Explorer V8 5.0 AWD

2002 ford explorer xlt 4.0 timing chain tensioner?

I'm thinking about replacing the timing chain front and right side tensioner it rattle doing cold start then when warm it goes away. I never worked with this type of vehicle and little worry about timing chain moving while I take the tensioner out. Any hint on how to remove this tensioner without going into bigger trouble.

How much can I sell it for?

My old 94 Ford Explorer XLT died on me today, the transmission decided to give out and spray it's liquid everywhere.

The paint is faded and peeling, the interior isn't great, and the back windows went out (which I heard is a little common)

It's got less than 200k miles on it but I just want to see if I can even sell it for anything on craigslist since I can't afford to get anything else at the time and the little money would be nice.

Why do you need a grade 8 bolt on struts, I have a 02 Ford Explorer xlt and I my friend just picked up a bolt and had me use it, it was 5/8?

Added (1). 6 inches long with 2 inches of thread, should I be worried about them breaking a day after hitting pot holes…

Added (2). I'm guessing it was grade 4 or 5 since it was 5/8 diameter, but I have no way of knowing… I called them earlier and had them save the last 2 grade 8 bolts

Horse trailer electrical to my truck

I have a 2010 Ford Explorer and I'm getting ready to purchase a 1980 Imperial 2 horse trailer. My truck and the other owner s truck have a 7 prong connector and I need to know if there's wiring that connects from my truck straight to the trailer or if it just connects right to it without wiring. I have not seen the trailer in person or tried it out as it is too far away to make more than one trip.

2003 Ford Explorer with a seized engine, no signs, noise, smoke or warning. Just came to a stop on Highway

I have a 2003 ford explorer I bought pretty cheap hoping it would last me atleast the year. I had the oil changed and all that stuff at Walmart within the first 24 hours of having the vehicle. I hit a curb about a week later in a snow storm and popped the tire and destroyed the wheel, but had a full size spare in the back I had AAA replace after the storm. I drove it a few times around town after the little accident. When I took the Highway for the first time after the accident about 10 minutes into my trip the explorer started slowing down significantly to a point where I knew I had to pull over, and I lost power steering. There was no smoke, no noise, no real warning besides the slowing down. I had it towed to a buddy of mine who spent hours, days, weeks trying to start the explorer but somehow failed to do so. He said he towed my truck up to his house with his truck and a tow strap while is brother helped by sitting in the driver seat of my vehicle to make sure they didn't collide. This trip was less than a quarter mile up hill. I had it towed to an auto dealership a few weeks later where right off the bat they said they were able to start it (which my friend somehow was never able to) but they started it heard a knocking noise and turned it right off. I was skeptical and upset. I had it towed to a mechanic that a few trusted friends told me about. He told me the tie rod was broken and that seized the engine hence the knocking noise.
