Guys, a little help I just need to validate the information I collected from all the sources that I have called and asked.

So my Hyundai Accent of 5 years now has a steering problem. When I brought it to the Casa, sabi nila the MDPS needs to be replaced, kaya lang sobrang mahal like nasa 90K. So i sourced for external parts and services.

After a series of asking and searching kung san makakakuha ng parts, I ran across Goodgear who is offering a full steering column (wala nun MDPS lang, wala ata talagang ganun) for 30K which includes UPP, MDPS and Tilt. I asked for a picture of the part which they gladly gave me ,then I asked Casa back kung ito ba yun talaga, they said yes confirmed.

Then nagtanong-tanong ako sa mga Casa kung sino pwede maginstall, one Casa said pwede naman daw, labor fee lang - they would install, which includes wheel alignment and calibration. There's an additional fee if I opt na merong pang re-evaluation. but wala itong warranty

Yun Casa kung san ako nagpadiagnose, hindi daw sila nagkakabit. Kailangan daw sa kanila ko rin bibilhin yun part. With that amount, magddown na lang ako sa bagong auto.

So my questions really are
1.) Tama ba yun part na bibilhin ko (for validation lang) - Steering Column
2.) Is it OK not to have the warranty for the labor?
3.) Am I already on the right path? Should i go with this na?
4.) Wala na bang kulang na steps na need ko pa gawin?

Thanks in advanced.
