I recently purchased a 2010 MDX Tech/Entertainment with 94,000 miles. When I test drove it, I heard a clunking noise from the right rear of the car. Having read up on this here on the forum, I had the dealer put it up on a lift, and checked things out. Sure enough...a badly leaking shock. Wasn't a deal breaker for me. Came home and ordered KYB's from Rock Auto, and a few days later, they arrived and I went to put them on. To say the old shock was shot was an understatement...I compressed it, and it never rebounded! I had no problem removing the old shock and replacing it...but when I moved over to the other side (driver's side), I could not, for the life of me, break the lower shock mount bolt loose. I tried heating it with my little propane torch, to no avail, and then sprayed it with PB Blaster and let it soak. I broke out my electric impact gun, and hit it with that...but it wouldn't budge. I had an appointment at my Acura dealer a couple of days later, so I asked the service writer if he could have the techs break it loose for me, then snug it up so I could get it home to change the shock. At first, he said no problem, and even told me that there'd be no charge. But later, he came out to the waiting area, and told me that the techs said that to remove it, they'd have to heat the bolt, which would most likely cause it to not thread back in when I went to install the new shock. Their advice was to bring in the shock that I had already purchased and they'd install it for me....to the tune of $200! I told them to just leave it alone, went over to parts and ordered a new bolt, and will have a local, independent shop remove the old bolt for me. Has anyone else had this problem? Apparently, it's an Acura/Honda problem, as I've had the same problem when I went to change the rear shocks on my daughter's 2008 Honda Civic. I've changed lots of shocks in my time...but I've never had as much trouble with shocks as I've had with these two vehicles!
