2003 Trailblazer 37.000 miles and changing gear

try it in Neutral instead of park. 4lo is geard so low that it can only be put in 1 way (for the most part), as for 4hi is more forgiving to put in.

Yep, it's setup like any pushbutton part time 4x4 system. You have to be FULLY STOPPED and in NEUTRAL to engage 4lo. Park wont work, and if you are rolling or moving it wont work.

Yes in neutral I did it and switched to 4LO and now I have another problem.
In 4HI I drove the car half a mile or so and in a left turn tires felt like locked up and I stoped and realize that back of the car lifted up? I got in to car and switched to 2HI and rightaway car went down.
Again I tried later on 4HI and in a sharp left turn car did the same thing.
Any idea what is going on or anything I should know.
In 2HI mode no problem at all, AWD mode also has no problem.

when in 4wd DO NOT turn sharp on dry ground it can damage the front end. when turning and the front end starts hopping that means u are to sharp. A4wd works fine cuz its not engaged until the rear tires loose traction then it automatically engages thfront tires until traction is gained and then it releases the fron tires. how high was the rear end?

[Salacak]

I have to say around 5 inches or so, when the sharp turn comes this is normal? I don't have to worry anything?

the hopping front end is normal, but dont do it. even on slippery surfaces when turned sharp you'll feel the front end kinda binding so on dry where there is no give for tires to slip the front end takes the abuse and being in 4 low that much tork could really do damage if rolling and turning. as far as the back end being that high, i know its not normal but i never turned that sharp in 4 lo so i couldn't say if mine raises up to compare. If it goes in all the 4wd gears the way they are suppose to it should be ok, just remember not to turn really sharp while in 4hi or lo, A4wd is fine to turn sharp in cuz you wont be losing traction.......typically.

Thank you for your replies.I really learned a lot from you.
Seems like everything is okay now. So if it is a heavy rainy or snow day and you driving in 4X4HI and had to make a sharp turn what do you suppouse to do? Stop and switched to 2WD and turned back to 4X4HI later or after every turn?
Thanks again

the only time i use my 4wd is in the snow. i never use it in the rain. if i were to, i would use A4wd then there is no issue w/ turning. i can drive through town in the snow in 4 hi and turn corners no problem. the TB has such a steering radius that you really have to be turned sharp to notice the front end. next time you get snow on the roads, do a u-turn (in 4wdhi) and you'll feel the front end not turning as sharp as it should be. turning corners or maneuvering through town u shoukldn't have any issues.......just no 4lo on raw pavement, if u must play in 4lo, wait for snow or mud or find a straight away on grass or dirt if u wanna feel the tork.....have fun
