Car Forum / Ford / Ford Trucks / June 200598 F-150 4X4 Question
I bought a 98 F-150 last year. It runs great/drives great but when I use 4-wheel drive and attempt to make a tight turn it seems to put a noticable strain on the trransmission. The truck has a 5-speed transmission and I really have to give it more gas to make the tight turn. I have and Explorer 4X4 too and don't notice any problems making tight turns in 4X4 mode. Any ideas on what might be wrong? thanks Phil > I bought a 98 F-150 last year.

Thanks for duh response but what about driving on icey or snowy conditions in Colorado? Phil >> I bought a 98 F-150 last year.

I have lived in the So Calif mountains for the last 20 years where going for 2-3 weeks straight with the hubs locked is common. However, Just throw the Transfer Case lever into 2wd when moving from ice to non-ice. When the roads are icy you can leave it in 4wd all the time. : Thanks for duh response but what about driving on icey or snowy conditions : in Colorado?

Most likely there is nothing wrong with it. The CV joints aren't perfect and when you turn them at a sharp angle, they are going to have some resistance. Try not to make tight turns in 4wd and don't worry about it.

I'll stop worrying about it. thanks P2 >> I bought a 98 F-150 last year.

Any >ideas on what might be wrong? thanks Phil The Ujoints used in in that type of axles and all striaght axles at that, are not constant velocity and they will bind more the sharper you turn the wheel because the joint is trying to speed the wheel up and slow it down twice with each revolution. The result is tightness and a binding feeling as well as some steering wheel whip too. It is also compounded by the fact the the rolling radius for front axle is more then rear tires since they take a wider arc in turns. A truck with true IFS (like GM’s) have true CV’s in the front axle and they bind and lot less and steering wheel "whip back" is non existant too. >>I bought a 98 F-150 last year.

The front is binding up simply because in a turn the 2 wheels move at different speeds and on dry ground, one can not slip. It's normal. Ignore it. >I bought a 98 F-150 last year.
