lurching in 4x4????

[ooja3k]

why does the car kinda lurch when making tight turns in 4x4.???

is this bad????


thanks

define lurch...

 

[ooja3k]

it feels like it is getting hung up and then releasing avery second or so when traveling slowly around a corner, and i happend to be in 4x4 when parallel parking one time and it would not idle forward or back because it was getting hung up so i had to hit the gas to get it to move and even then it kinda jumped.

hope this definition helps of "lurch"


any ideas? is it just not wise to turn tighter in 4x4?

You must have part-time 4wd. If so, don't put it in 4WD on dry pavement and it will stop "lurching".

ooja3k, biglatka is right, I wouldn't drive it in this mode on dry pavement. I used to own a 4WD Toyota extended-cab pickup and it would do the same thing on dry pavement when the hubs were locked in and 4Hi or 4Lo was selected. Think of it like this: when you make a turn, one wheel needs to turn more (the outside wheel) than the other wheel. But with the differential locked, both wheels are turned the same amount. No problem if you are driving straight ahead, but when you make a turn, something has to give. On snow or sand, this wouldn't be a problem.

i don't think i have a locking diff tho, i have a 97 limited 4x4. it doesn't have a diff lock switch. does it have a center diff and lock anyway????

solargroovy is 100% right. the lurch you feel is that wheel spinning on the pavement. It is extremaly bad for your car. Even with out the locking dif it will do it.

Since you have a 97 Limited 4WD (96-98) shifting into 4WD splits power 50/50 front and rear, basically locking both front and rear driveshafts.

earlier 3rd gens have a "part-time" system and should not be used on road (ie high traction surfaces) that lurching is the driveline binding- since wheels need to turn at diffent speeds when making turns. as said earlier, sand, snow, gravel, (ie off road) will allow the slippage needed for tight turns preventing binding .the newer models with the "multi'mode" system has a center diff which will allow for the needed "slippage" front to back and can be used on the highway. the earlier part-time ones shouldn't be used on road.

Thats the main reason why I should have purchased a 99-00 Limited w/ E-Locker instead of my 97.
