This was the perfect hitch for my 2002 ML500. I did not need a higher load rating for this car and I wanted something that looked as close to a manufacturer install as possible. The dimensions of this hitch allowed for that. Only a small relief cut of the bumper cover was needed. The installation was straightforward. The instruction video for the lighting module was helpful. However, I will say routing the power lead from the left rear taillight to the right front battery location is a bear if you want it to be well secured and hidden. I recommend taking the time to clean up and lube the spare tire assembly. It will never be easier than when doing this install. I also suggest that cutting out the facia plate so that it can be used makes a huge difference in the final appearance. Trimming out the cut with some fuel line adds a finished look. Thanks for a great product and a truly helpful website. 202403

Mercedes hitch installation After several web searches through my ML Blogs& advice from Engineers at work, I was able to complete the task in 40min! * took the bumper off by sliding it straight back after removing qty 4 screws located behind 3 bumper covers * inspected the hitch + instructions * inspected holes on car bumper, making sure that there is no debris in holes (used wd-40 in one to lube bolt in) * installed hitch * re-installed bumper * took the longest time because it has to be aligned to the guides on each side of the car * center attachments also had to be carefully re-aligned due to the size of the hitch * two people is recommended for a faster re-install Hope this helps future buyers... I attached some pictures...thank you for the awesome product! 4715
