Type-44: pressing hub into front wheel bearing

Wed Nov 26 18:33:27 EST 2003

Yea, this was actually pretty easy and took me and one of the shop workers about 15 mins. to do the whole thing. There are 2 snap rings as Eric mentioned. I first put the one in facing the hub/wheel, then we pressed in the bearing from the other side. The wheel side of the strut housing has a flat lip around the bearing area and was better to use as a press surface than the rounded portion on the other side of the strut housing. We just pressed the bearing in until it hit the ring. Then I popped in the other ring and setup the press for the hub. We supported the inner race of the bearing and put a flat block over the front of the hub. We pressed the hub until it also "stopped". Seems pretty good now. It's not extremely free when turning, but it's very smooth, so I guess nothing got damaged. We'll see if the bearings burn out when the car hits the pavement, whenever that is...Oh and thanks a lot for the responses.

But he asked about pressing the hub into the bearing once the bearing is
already pressed into the housing. The snap rings are on both sides of the
bearing, not the hub.

Ameer, IME once you press in the hub you cannot remove it without
destroying the bearing so don't forget the second snap ring before you
press the hub into the bearing because. BTDT. I continue to run it that way
without a snap ring and I have no problems. I check it periodically and it
has not moved at all, but I always wonder how much factor of safety I am
losing without that snap ring in there.  That bearing presses in so tight
that the snap ring cannot actually be doing much.

Hi Ameer.  I just did a rear one on my type 44 and I think it is similar
to the fronts.  There should be a snap ring in a groove in the hub.  The
bearing gets pressed in until it's snug up against the snap ring, then
the second snap ring can be put in.  Like I said, this was on the rear,
but I am quite certain the front is the same.
