We were doing up to 90 mph sometimes the speed limit is 75 mph and the semi trucks are doing 85.
After 6-7 hrs of driving you drive with the flow.

 

Well then you got what you asked for. Sorry, but that's the truth. Jeeps weren't made to "go with the flow". They were made to go slow.

 

You know your completely wrong here and I'm not going to waste my time with you arguing.

I guess when when the new 5:38 (?) gears come out for the people running 40" tires and they go 70mpg they'll " get you asked for too" .

 

WHAT? That might be your style, but don't push it off on others. I typically cruise at 80 and sometimes forget and go faster. It can handle it well as good as going slow. That's what a transfer case with lo range is for.

 

Sorry guys, I'm going to side with Redneck. The spec's of TrailBud's Jeep are tailored for off-road, not highway. Speeds in excess of 65-75 mph for long periods of time with a package tailored for SERIOUS off-road, you're asking for trouble. Everything rotates faster and thus will break down sooner. The out of balance driveshaft would have reared it's ugly head at some point down the road, it just came sooner because of the excessive speed.

TrailBud, why aren't you asking the manufacturer for reimbursement of damages due to a defective product?

 

I have to respectfully disagree with you here Redneck. They are very much designed to go with the flow, and not designed to go slow.

It's one thing if you have it in 4wd and are going that fast, but these aren't yugos we're driving. They are designed to reach highway speeds.

Granted, it may or may not be a good idea after you have upgraded shafts, gears, and whatnot - but the blanket statement that jeeps aren't designed to go fast is absolutely false.

I would say 90% or more of the people on this forum drive their jeeps over 75mph on a regular basis. I have put at least 20k miles over 80mph on mine.

 

An unbalanced driveshaft is not a defective product. Driveshafts have to be balanced just like tires. They usually come from the factory pre-balanced, but that doesn't make it their fault if it comes out of balance and then shatters.

I know Gokracer1 just went and got his driveline rebalanced, probably at the same shop in UT, because his driveline was off balance from the factory. It just happens sometimes.

 

Whoa, whoa, whoa - stop this madness. Again, 37inch tires are not OFF ROAD TIRES. Just because they have an agressive tread and are better for offroad doesn't make them offroad only. And being 37inch diameter doesn't make a lick of difference either.

 

I really don't know where all these statements are coming from.

What difference does it make if you have factory 29s or aftermarket 37s in regards to how fast they can go? Contact the manufacturer of the tire and check the speed rating...done. If it's advertised at a certain speed rating from the factory, then it CAN hold that speed without an issue.

What difference does it make if you have factory suspension or an aftermarket coilover system? If it's set up for the amount of lift you have without any binding, you can drive as fast as you did with the factory suspension on. If pinion angle and castger are set up to spec, you can drive as fast as you did on factory suspension. Period.

I just don't understand why bigger tires and lift will limit your straight line speed on the highway...

 

I'm not going to scold the OP like everyone else, but just reiterate his piece of advice as well as my own piece of advice and you can disregard at your own risk:

• Get your driveline balanced if needed
• Do not exceed nominal high way speed (65 mph) when setup for offroad use
