I have self-diagnosed my RAV4 with a wheel bearing going bad. One thing I noticed:
- During height of the day (10 am to 6 pm), when hottest: bearing scratching/grinding noise is loudest
- Otherwise: bearing noise isn't as loud
Does this match anyone else's experience? Does it make sense that increasing outdoor temperature can correspond with louder bearing noise?
I am wondering if this can help me further understand the noises my car can make.
My inclinations the wheel bearing is bad:
- Scratching/grinding noise starts at ≥30 mph (if hot outside) or ≥55 mph (if cold)
- Hitting brakes doesn't seem to affect the noise
- It continues for the entire drive (not a function of short or long drives)
- Car is a 2008 Toyota RAV4 with >200k miles, and I have beaten it up over the years
Full disclaimer: noise could be coming from brakes, I may be wrong in my self-diagnosis
