| RE: 4x4 hi and low speeds?|
The speeds you drive in while having your front end locked in should be controlled by the driving conditions. First, I wouldn't do any normal driving in 4 lo. I've only used 4 Lo to pull a boat out of a really slippery boatramp and to pull a guy out of a muddy ditch. 4Lo is more of a pulling gear and not so much as a traveling gear. So in my opinion, I would only use 4Lo in extreme condtions where you need maximum traction on SLIPPERY surfaces. Never use 4 Lo on dry pavement for instance. Now 4 Hi, is a different story. Everybody will have different opinions. Before I got my '02 Dak, I never drove my truck past 45 mph with her locked in 4 wd. But since I've gotten my new truck, I've gone much faster. I had her locked in at around 60 on the interstate durring a snow storm. Looking back, I was stupid. Not because I was locked in going 60, but I was going 60 in a snow storm. 4wheele drive is a godsend, but it doesn't make you bulletproof.
So I guess to answer your question, in my opinion, in 4 hi, you are safe around 55 or 60. 4 Lo, I would only use in extreme situations. And in those situations that warrant 4 Lo, you won't be going very fast at all. And like I said earlier, in situations where you need 4 wheele drive, you being locked in won't the the deciding factor as to how fast you can drive, it will be the weather and road conditions.
Hope it helped out.
