I'm in the process of replacing the 6 sets of taper roller bearings (and leaf springs and shackles while I'm at it). The axle is a 7000# Dexter. My question is do you have to (or should you really) replace the races at the same time as the bearings? The Chinese bearings have about 70,000 miles on them and I can't detect any wobble or wear but that could just be my lack of knowledge. If I do this I'll spring for SKF or similar manufacturer. I've heard of bearings causing Brinelling if left in a static position for a long time though I can't detect it on the stock races. This one of the reasons you put a car up on blocks if left static for a long time.
i've always just replaced the hubs from eTrailer.com bearings and races were only slightly cheaper than just replacing the hub itself for me.
I posted this before on another trailer issue. I’d recommend changing the bearings in sets of the same manufacturer. The best taper roller bearings are USA manufactured Timken. They’re worth the extra money.
If he has 7 k axles, he has drums, lots more $$ than doing bearings. Always change the races when changing the bearings!
Oh... I thought this was about trailer park Tammy and Kid Rock. My bad. Google that, for some entertainment....
If you Google the keywords I posted above, Mr. Bag-o-dicks better find a jimmyhat first... OTOH, Kid Rock has more musical talent in his left pinky fingernail than 98.6% of the people who make their living in the music industry these days.
Change bearings in full sets, Kid Rock is awesome. <Checks the box> Next? Brinelling. For those suffering from mild curiosity or, like me, don't know if ya ever really knew... https://www.rexnord.com/blog/articles/bearings/what-is-brinelling
Just like so many 'U.S.' companies, Timken's bearings and whatnot aren't necessarily made in the US. Sourced out to 42 other countries....Taiwan, Indian, China etc....
True enough! That’s why I said USA manufactured. Fortunately, Timken still has lots of facilities in the US.
Motion Industries used to deal in USA, German, and Japanese bearings. Last time I was in there, everything on their shelf was Chinese. The counter guy tried the old line of “There are different levels of Chinese bearing.”. Pfft! Bullshit. They’re all garbage, when they’re all made from the same Chinese base material.
Timken used to have a long history blurb on their website detailing their progress. Some of their significant advancements were vacuum degassed steel and Timken-izing the railroad and automotive industry
