I have not yet had the pleasure of removing the rear drums on my Avanti, but I have read that sometimes it is difficult. I ran across some hydraulic hub pullers and wondered if anyone has tried either one of these:

Okay, here is the D.I.Y. version, go to bottom of link

Note that you should first check to see that your bottle jack will work on its side.

Next up, from somewhere in the orient, I'm not sure but it probably is a JTC piece:

Of course the manual versions still work

Yeah, I know this is the $49 ebay knockoff of the OTC/KD Tools hub puller - although I'm not entirely sure that the OTC/KD hub puller is still U.S. made.

I wouldn't use a hydraulic puller for tapered axle hubs. The reason, IMO, is that the hurry-by-force method could result in breakage or distortion of the hub possibly. Maybe even injury!!

The mechanical means are slower and safer, I would think.

The hydraulic one does look cool though.

I'll admit to being surprised that the hydraulic hub remover is apparently an exotic tool that none of the regulars here have ever used. While it is true that the home-brew bottle jack could possibly apply way too much force on a reluctant hub - the ram on the JTC puller is fairly small by comparisson to any bottle jack. I think that is done to keep an excess of force from being applied.

Ever used? H**l, we've NEVER heard of it!

I would go with the mechanical puller. The key to breaking the taper is to apply pressure with the screw, then giving the top of the screw a whack with a BFH. The impact of the hammer shot will separate a taper better than a straight steady pull.

Be sure to install the castle nut backwards on the axle, flush with the end of the threads, while you are using the puller. It will prevent damage to the threads, and keep the hub/drum from flying when it does pop loose.

What he said. And also make certain that the lug nuts holding the puller arms are tight. To not do so will likely damage the wheel studs.

Go with Rerun's instructions. Removed the drums this AM on my '63 Avanti. No problem. Buy, Beg, Barrow or steal the best drum puller you can get hold of. Don't use the type that pulls on the outer edge/surface of the drum, unless you have replacement drums on hand.

Given that none of us had ever seen a hydraulic hub puller before, that can only mean one thing - that the Chinese tool companies have moved beyond copying, and now they are innovators!

That JTC hydraulic hub puller seems reasonably well thought out. It has a smallish hydraulic ram to keep from overpowering the job, and it has five pulling fingers for even load distribution. Amazing.
