I need to find out if I need to activate the 4 wheel drive for snow driving on the freeway. I have a 1986 Grand Cherokee. V8 5.2, with abs. There is a lever for lo/hi but I think that is used only for...
That is up to your preference in my opinion. 4 wheel may give you a little more traction, but it can also lead you into a false sense of security. If heavy snow, and you need to get through it, you can only go as fast as the guy ahead of you anyway right? Up here in Ontario Canada, I passed by many a 4 wheel drive in the ditch, because they assumed they would have a better chance on icy roads than me, with 2 wheel drive. Remember this, no matter what you decide, you may be able to go a little faster in 4 wheel, compared to 2 wheel, but when you have to hit the brakes, or go into a spin, 2 wheel or 4 wheel drive, your not going to be able to stop it any faster. Your going to use more gas in 4 wheel too. Yes there will be times when you need to use it, but like I said, when it goes sideways or you have to lock up the brakes, because you were pushing the envelope too much,? At least with 2 wheel, you feel the back end break loose, to warn you how slippery it is, and you may not feel that soon enough, with 4 wheel. Just my opinion, but maybe some 4 wheelers have a different opinion. It's just like the experts from the skid school said up here about mandatory snow tires being talked about. If putting snow tires on your car is going to make you drive a little faster, your defeating the purpose.
I fixed my sluggish jeep Grand Cherokee Ltd 2000 by lubing the "knuckle ball stud". The owner's manual requres this service about every 6,000 miles, but only Jeep dealers have the tools and know how to lube it. i still don't know where it is located, but it worked.
I am not sure what you want to know, please explain and leave out any un-related info, it just confuses the issue at hand Has it been tuned, has the fuel filter been replaced? is the fuel pressure ok? does the system have any trouble codes stored? has the check engine light ever come on?
