That sounds simple enough to do. I will give it a check this morning when I get off of work.

I keep getting suggestions that the tires are most likely out of balance. I haven't had tires be perfectly in balance at low speeds and then out of balance at higher speeds. Is that a possible factor here?

Ok, I'm sure I could get away with just running the aux cooler for a short while. I am looking at dropping in something like this cooler up front near the aux cooler if I have space. Then the only thing I would have left to do is hook up a couple of pull fans on them. I haven't looked to see how muc...

I've read that thread and a few others on other sites and I'm not so comfortable just disconnecting the Rad-Trans Cooler without supplementing it somehow. I do a decent amount of trail riding and stop and go traffic. While it's winter here now and the temps aren't too bad, once 100+ degree summer ge...

I feel some what lucky, but not that lucky... Which means I will be doing a By-Pass pretty soon. I guess I just wanted to hear it before I started buying parts and slapping them in.

What's a good way to check the U-joints to see if they are good or bad? Unfortunately I don't have the funds to start replacing every part until it's fixed.

Transmission By-Pass Still Relevant? 125,000+ Miles

Just curious as to what you guys think. My '05 Pathfinder has 129,000 miles on it without radiator failure. Do you guys think that it would still fail at this point or do you think I am good?

Vibration/ Harmonics at high speeds

So, I just got an '05 Pathfinder and took it on a 1200 mile road trip to West Palm for a week. While I was driving the highways I noticed that it starts to rumble a bit once you hit 80mph or more. It's like a subtle vibration or harmonic build up in the frame. If you've ever had mud tires on a car i...
