Sender: Forward Look Mopar Discussion List <L-FORWARDLOOK@xxxxxxxxxxxxx> From: eastern sierra Adj Services <esierraadj@xxxxxxxxx> Subject: [FWDLK] STUDS: The HUB of the matter X-To: David Homstad <dhomstad@xxxxxxxxxxx> To: L-FORWARDLOOK@xxxxxxxxxxxxx
All right: 1st of all, you engineering-types (cept for Dave Homstad) haven't exactly jumped in on this thread, that I'm hanging from.
Also, I was not present when my shop replaced Horrie's swaged brake drum studs, which allowed the brake "drums" to slip-off of the rear axles, without the necessity of using a "wheel-puller" (any longer).
Welll, I went back to my shop, today, with my souvenir swaged stud (that I keep in my office, for old-times-sake) and with the 2 WPC Club articles that I authored (vols xviii/#7, 3/87 ; & xxii/#2, 10/90), and told him to splain hisself.
He said that the central "hub" area is actually a SEPARATE piece, from the outer "drum" section, and that the 2 pieces are held-together (thanx to Chryco's renowned over-engineering) by the swaged (press-fitted) 'shoulder-sections' of the studs that are installed from/through the underside of the center-HUB section-piece. I had been led to believe that the "swaged-studs" which prevented the easy removal of the drums were the studs that are installed from the rear of the AXLE-FLANGES: wrong!
Actually, the axle flange studs ARE 'swaged' into the flanges, but they're not responsible for holding the hub/drum to the tapered axle (as Lou & Dave have asked-about).
SO, once the hub/drum assembly is "pulled" off of the axle, the HUB studs can be replaced with the 'standard round-shouldered' studs, so that, once the hub/drum assembly is re-mounted to the tapered axle (using copious "anti-seize lube" on the nexus of the hub & tapered axle) here it comes--------in the future, the "standard" round-shouldered studs will allow the outer drum-section-piece to SEPARATE itself from the hub-section-piece (which remains 'mated' to the tapered axle, and which WILL require the use of a puller, to remove----however, the only reason for the 'pulling' of the hub would be for a servicing of the axle bearings, which are internally lubricated (right?), and which usually only require "replacement"(?) .
ALL brake "servicing" can be performed with only the easy-removal of the drum-section- piece, INCLUDING "turning" of the drums!
Now, "this" was the way that "the-deal" was splained to me.
Kinda interesting, huh?
