Replace front brock sway bar on altima 2003

Check the drive shaft universal joints. Also possibly an alignment problem.

go find an other garage .but as for the cost .just search online.

You must be asking about the front sway bar links. It would be very unlikely that you would need to replace the sway bar, unless you got in an accident.
I had to replace the sway bar links on my 2002 Escape. They rattled like crazy.
The bars are pretty cheap; about $10 each, from Autozone, for example. But they can be difficult to replace. The upper nut can be tough to get off.

Definitely the sway bar links. New links are extremely stiff at the balljoint. Old ones appear OK until you compare them to new ones.

yes they are the same. 8 months sounds premature, but if it was an inexpensive brand X part they used it is possible.

Not difficult. Just hold onto it so it foesn't fall on you. Remove the front clamps fist

just bushings. unless the bar itsef is damaged (cracked, bent, broke, etc) just replace the bushings.

may be boll joint
or sway bar link .

i heard it could be the steering column

Had similar problem with 2003 Dodge GC. Replaced the parts you mention + rack & pinion, then to fix the now noticable whining noise, replaced power steering pump and pulley. Fortunately was under an extended warrentee at 46k miles.
