First Lexus! Upgraded from a 2010 RAV4 to a 2009 RX350 AWD, excited but got a couple things to sort out
Just picked up my first Lexus after years in a 2010 RAV4 (RIP, it got totaled). 2009, Pearl White, 136k km (84.5k miles), AWD, and honestly the ride quality alone has me sold already, this thing is so much quieter and smoother than the RAV4 ever was. Got it for $13.8K CAD. No accident history and everything was in excellent condition.
Bought it as-is knowing about a couple issues going in, now trying to figure out next steps and would love this sub's input since you all know these better than anyone.
- Steering rack boot is torn (photo 1), grease visible at the tear. No play or clunking when turning the wheel, seems to drive fine. Anyone dealt with just replacing the boot vs the whole rack? Trying to gauge if this is a cheap fix or if I should just budget for the full rack.
- Front diff housing has some oily residue on it (photo 2), fluid level checked out normal. Does this look like a typical slow seep for these at this mileage?
- I'm assuming getting both repaired in one go would be cheaper way to go in the long run in term of labor costs?
Excited to join the RX350 club, just want to go into the repairs with realistic expectations. Thanks in advance!
