Question Installing Front Wheel Hubs on a 240

I'm redoing the front suspension on my 240 including the bearings. I've gotten the new bearing seated and I'm trying to get the hubs back onto the spindles. My question is, how much force should I expected to use to get the hubs on? I've made a few weak attempts to just push them on by hand but, unsurprisingly, the fit is tight and I can't get them on that way. Do I need to hammer them down? What's the best technique?

Pretty sure you install the races first and then it slips together.

Are you putting the correct year bearings on the hub?

Late spindle,,, early bearings perhaps?

Is that a thing? I have a 92 and bought

https://www.fcpeuro.com/products/vol...-262-264-265-1

which claims a fit. It doesn't mention later or early bearings.

Do you have the bearings pressed into the hubs? They should slide right onto the spindle by hand with pretty much no force if the bearings are pressed in straight. I just used the same skf bearings in late model hubs for my bne coilovers.

So it turns out that I do have the correct size bearings but I was underestimating the level of centering accuracy needed push it on cleanly. It's a tight fit so if you push somewhat unevenly the bearing has a tendency to get hung up. After messing with it for awhile I managed to slide the hub on without issue, so that showed that it's possible. What I found that helped make it an easier process was to put it on as far as I could and then thread the castle nut onto the end of the spindle without the outer bearing in place. They helped center up the hub, and the act of slowly tightening the nut down gave good lateral force right along the center of the spindle that pushing along the edges of the hub did not.

Thanks for everyone's help!

Make sure they're not too tight or you'll spin a bearing and need new hubs & bearings.

I guess it all depends on your particular version of "tight".

Doesn't take much end load to burn up a roller bearing.

A little late but for what its worth these are excerpts from Volvo manual TP 11050-1, Suspension and Wheels:

Grease the bearing with a grease press.
lf a press is not available, pack the bearings by hand
with as much thick grease as there is room for
between the roller retainer and the bearing inner
race. Also apply grease to the outer sides of the
bearings and on the outer races pressed into the
hub. The recess in the hub is filled with grease all
round up to the smallest diameter of the outer
race of the outer bearings.

Adjust front wheel bearings by first tightening
the nut with a torque wrench to 70 Nm = 50
lb.ft. Then slacken the nut 1/3 of a turn. lf the
slot in the nut does not coincide with the cotter
pin hole in the stub axle, slacken it to
enable the cotter pin to be installed. Check that
the wheel rotates easily without any play.

Fill the grease cap half full.

No worries. I tightened them down mostly to make sure the bearings are completely seated and then backed it off to make sure the wheels spin without issue.

Like finger tight on the verge of being loose.

NB:

There's horizontal & vertical holes for the castle nut's cotter pin on a late spindle.
