High quality OEM replacement wiper
Very satisfied with the OEM replacement wiper arm assembly I received from 1A-Auto. Ive seen some wiper arms without the hose included. This one has the hose and is already attached. No need to remove the old hose and attach it to this wiper arm. This high-quality replacement was delivered faster than expected. I am extremely pleased that it fits just like the original part it replaced. It took barely 5 minutes to install. I simply wiggled the old one off and placed the new part on the knurled post, then tightened the nut. Done. Works great. Now I can see out of my rear window. Smokey wont be sneaking up on this guy any time soon (kidding Smokey). I drive safely. :)
