    Questions about installing SET39 bearings in 1999 SL2

    I am considering going with the SET39 tapered roller bearing for my 1999 SL2.
    I just got the car and the left front is howling pretty badly. I have changed bearings and hubs on my 1996 SC a few times and have a 20 ton press so the mechanical work isn't the issue.

    My experience with tapered roller bearings has always been rear end or the hub in rotor kind.
    Is there any specific way to install these SET39 bearings as far as inboard or out board?
    Do they generally last longer than the Timken ball bearings for the S-Series in daily drivers?

    Properly installed moogs/timken/namebrand will last just fine. They are a around a 5-10 year maint item typically, if not longer.

    Make sure your hub is within spec. I have seen too many people go through a few sets of bearings cursing the bearings when the hub was out of spec after the first one went out.
    It's not my fault, blame the radiation.

    Okay, thank you for the replies, I will probably just get the timkens with new hubs.

    Check the knuckle as well, for piece of mind.

    How do you go about doing that?
    Will measuring the diameter of the hole in a few spots give me a good enough idea?

    Rather than start a new thread, this seems like a recent enough post to which the answer to my questions may be of use to others changing front bearings for the 1st time.

    1) In which direction do you press out the old bearing? Inward or outward? Or is there a physical stop on one side that answers that question?

    2) What "object" do I use between the the bearing and the press to ensure I am not distorting/destroying the outer race of the bearings during the pressing? Is there some "device" that is exactly the right i.d. and o.d. that you folks use to avoid damage?

    Apologies for the rookie questions but my 97 SC2 still has factory original bearings all around at 258K and the front bearings are becoming problematic.

    This is my daily driver so it has to go back together at the end of the work session, even if the hub is out of soec, until I can go parts picking for an old one per your earlier advice on the subject (vs a new shitty Chinese one.

    Thx

    You will push the hub through the bearing from the backside. You will also see the snap ring that holds the bearing in when you have the knuckle out. The bearing will press from the road side to the car side out.
    For properly supporting the bearing I have a bunch of 3/4 and 1" steel pucks I made but I do bearings fairly often. You can get kits like this that have a variety https://www.princessauto.com/en/deta...et/A-p8311565e
