2 different types of bearing/hub assemblies?

So Ive been having some grumbling and vibration coming from my wheels, figured it was wheel bearings. Had a mechanic come out and look at it who told me there is two different type of bearing/hub assemblies. One that simply bolts on and another that involves a lot more work. Is there any truth to this?? Hasn’t heard this before he checked it out tonight.

 

Well………..Technically an assembly is “assembled”.
Which means it is all together.

So, No. there are not 2 different assemblies.

What he means is, you can buy it prebuilt.
Or you can buy the pieces and build it yourself. Which requires more work.

Just buy the assembled unit (assembly), and bolt it on. Cheaper.

 

He's probably referring to 5 lug (2wd) vs 6 lug (4wd & PreRunner (2wd w 4wd suspension))

On 5 lug trucks the bearing and hub are pressed into the knuckle and as such the knuckle has to be removed to replace the bearing.


On 6 lug trucks the bearing and hub bolt onto the knuckle so they are much easier to replace.
These are sold either as pre-assembled (new hub is already pressed into the bearing) or as just a bearing (you have to press your hub out of the old bearing and press it into the new one).

Your truck being a 4wd will have bolt on hubs/bearings.

I kind of assumed a “mechanic” would have looked up, or known that information?
I think this is a case of poor communication, or lack of knowledge.

Either way, OP has the “easy” truck to work on in this case.

 

guy on here sells good kit. They bolt on. Done.
