I wish I had taken before and after photos, however it was a long day in the Texas summer heat and partially in the sun, replacing my wheel hubs on the back end of my 2013 Nissan Altima sedan, but I was also doing the brakes and shocks at the same time. I had a lot of noise with what I believe to be the original wheel hub bearing assemblies. We got the car with 146,000 miles and now it has 309,000. Going down the highway we can hear whirring and slight buzzing noise from the back of the car.I have purchased TRQ control arms for the front of the car in the past and they are still going strong 2 years later, so I have a good confidence level with TRQ. These wheel hubs were a good price and they fit perfectly on the rear suspension knuckle and were easy to install (considering the odd angle for accessing the mounting bolts due to Nissan design).After a week of driving down the highway and along city streets, the ride is noticeably quiet. Now all the noise we hear is the tire noise. I'm very happy with the purchase and will get TRQ again.
