I replaced my Subaru Outback 2015 2.5L's rear right lower control arm (Part number: 20250AL01A) about 6 months ago. Originally, the squeaking was pretty bad over bumps which led to me replacing it - but it has returned a couple of months back.
It seems like it's squeaking where it attaches to...
So... first I had a defective battery but by the time I realized it wasn’t my fault it kept going dead they said I had already driven too far for the warranty :-( Got new battery & have had it for 1 or 2 years & was driving but noticed car was dragging like the brake was on, airbag light came on...
