Thrawn Posted October 7, 2011 Share Posted October 7, 2011 Hi, been lurking around here and really like the board, been meaning to make an introduction post, but work keeps me pretty busy. Have one Mack I'm working on that lost a wheel bearing and ate up the stub on the axle. I noticed the stub is removable, but the Mack dealer we go through says they don't offer just the stub and the whole housing will have to be replaced. Does anyone know of an aftermarket manufacturer that offers these?Thanks. Quote Link to comment Share on other sites More sharing options...

rhasler Posted October 7, 2011 Share Posted October 7, 2011 The cast or ductile iron housings have replaceable spindles, the fabricated housings do not. Quote "Mebbe I'm too ugly and stupid to give up!" Link to comment Share on other sites More sharing options...
Thrawn Posted October 10, 2011 Author Share Posted October 10, 2011 Definitely a cast housing. Quote Link to comment Share on other sites More sharing options...
rhasler Posted October 10, 2011 Share Posted October 10, 2011 The cast housings can be differentiated by looking at the bolts that lock the spindle in the housing. The older style have an external hex head bolt behind the brake spider flange (towards the center of the truck). The newer style have an Allen head lock bolt on the opposite side of the housing (toward the outside of the truck). The newer cast housings use a spindle that is supplied by Renault. They are sometimes in short supply domestically, but they are commonly available, our shop replaced one about a week ago. Replacing the spindle is going to take some special equipment, or you can pull the housing and have a machine shop with a lay down press push the spindle in and out for you.

Thrawn Posted October 10, 2011 Author Share Posted October 10, 2011 Yes, I know it's removable I need to know of a part number or a supplier, we're trying our Mack deal again today to see if we can get another person on the phone. I won't be doing the repair, a machine shop next door will. Quote Link to comment Share on other sites More sharing options...
rhasler Posted October 10, 2011 Share Posted October 10, 2011 Tell them to reference SB 471-001 New Cast Axle Housing Replacements (Feb. 6, 2007) Quote "Mebbe I'm too ugly and stupid to give up!" Link to comment Share on other sites More sharing options...

theakerstwo Posted October 24, 2011 Share Posted October 24, 2011 I have seen them in our shop many times. Most of the repairs was caused by the TA truck stop shops.Many wheel seal replacements went bad from them and then they are told to go to freightliner for warranty.

Thrawn Posted October 24, 2011 Author Share Posted October 24, 2011 Yeah we ended up going through axle surgeons, did a great job, fast too once we got the paperwork approved from the higher ups. All we had them do was replace the spindle, I did the rest after that as I wanted to replace the bearings and brakes on the other sode as well.
