Misc Front wheel bearing size?

[ram137]

I have an 85 CJ7 with the Dana 30 front axle. Were different wheel bearing and race sizes used for different years. I have some play in the front left and would like to go ahead and replace them instead of just repacking. Unfortunately, when I look online to order them, I’m finding different sizes available.

Yes, there are different sizes of front wheel bearings for a Jeep CJ7 , specifically related to the inner bearing. The outer wheel bearing is the same for both drum and disc brake axles. However, the inner wheel bearing differs: drum brake axles use the same bearing as the outer, while disc brake axles require a higher-rated bearing with a larger inner diameter bore

It’s my understanding the CJ7 always had disc brakes up front. Is that incorrect?

Nope they were an option in the early years of the 7
