Steering wheel column very loose only holds in up position

Take it to a shop where they know what they are doing.
Almost sounds like the care was in a wreck and improperly repaired.
I highly recommend you not drive it until you discover the problem.
Some part you have not mentioned are the steering column, the steering box where it is fastened to the frame, the motor mounts, and the steering knuckles holding the front wheels on.
God bless your efforts.

There is one adjustment to the steering gear, but this doesn't remove very much play in the steering. And once set, I have never seen them back off ( it's the big nut on the back of the rack, break it loose, then turn the inner nut, Just a little through. You get it to tight and it will be hard to turn). If you have a lot of play, look at the tierod ends, inner and out. There are also two universal joints on the steering shaft that could cause a lot of play. One by the rack and one under the dash. There are bushings/bearing that hold the steering shaft in place, These don't cause much left or right play, they will cause the steering wheel to be sloppy at the column.

The wiring for the steering column is inside the column. What do you need to do? Be careful if you do not know what you are doing. If you need help let me know.. I work on cars.

It appears by you description that the position lock is not clamping up. position the wheel where you want it and look just under the dash for a lever or knob that will tighten up and hold the column in place.

check to see if the bolts aernt striped that holds the clampe that holds the ajustebel steering

Is the steering wheel its self coming up or the shaft were it connects in the floor coming up. This would help me solve your problem . If its the wheel there is a 18mm nut behind the air bag that holds the steering to shaft.
2ND If it is in the floor shaft there should be a bolt holding the two shafts together, you might have to pull carpet back to see if bolt is in the slot that holds the two shafts together.
If i can be any help just repost. Thanks, dodge tec

Just an fyi it is the steering wheel and column assembly. Nissan suv's and trucks are NOTORIOUS for having the upper bearings inthe steering column sheer and or go bad, HUGE safety issue.

Replace the steering box - check junkyard for one of similar model/year or ask Pep Boys to help by cross ref. your make/yr with others. Pep Boys will even install for you.

it sounds like all you need to do is as follows, remove the steering wheel and behind it inside the column you will find a couple of screws or bolts that hold the tilt steering assembly together, they have most likely come loose and just need to be retightened , I would recomend that when you have the bolts out that before you reinstall them you put on some kind of thread locker (ie) lock tite. this should solve the problem

Hi,

Try Check or replace the turn signal switch. It might have loose connections or its faulty.
