Nissan Sentra 2001 zipper

Greetings to all ...
I just bought a 2001 Nissan Sentra, it was apparently in perfect condition, but within a few days a noise in the front train especially when there is some deprecion an the road or when it is handled by some surface that is not paved. In addition the steering wheel begins to tremble at 90 kmh, it is very little but trembles. I think it is the zipper, lift both sides and there was no game. I think it could be a zipper wear or any defect per blow, is it possible to adjust the zipper?
Thanks in advance
Gonzalo

Hello, how about
the zipper has regulation.
But I don't think that is the cause of what is happening to you in the car,
is your box mechanical or hydraulic?

It is true what you say not cause of the zipper, you have to check the Valanceo of the pneumatic or wheels for the theme of vibration and noise can be some component of the suspension, Czech tray Rotula and shock absorbers.

The address box I suppose it is hydraulic

hello.
To know if it is hydraulic, you first recognize it in driving when you do not try to move the steering wheel. Another way to verify is to observe whether the hydraulic steering pump is located near the alternator.
luck....
