Popular Post convoyduel Posted Wednesday at 01:18 AM Popular Post Share Posted Wednesday at 01:18 AM Didn't find anything on a search. I have a 1989 R688ST with a FAW5371 12k steer axle. I need to redo the wheel ends. I know the outer bearing is a 45280. Does anyone have the inner and outer bearing and race numbers handy? Also interested in a wheel seal number and a spindle nut number. Some jackwagon used a chisel before. 4 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76131-mack-faw5371-12000-steer-axle-bearings-and-seal/ Share on other sites More sharing options...
The Heinz Posted Wednesday at 05:37 PM Share Posted Wednesday at 05:37 PM What's your VIN? I might be able to get you numbers for a Timken set.

Has a fire service air to her... Definitely going to need to see some more photos! I am the second owner. It was originally used to pull powder and end dump trailers for a ready mix company in Chicago. I bought 3 of their 4 R models when they retired them. I reworked this one into a St. Louis Fire Dept theme styled like their 1968 Mack R model pumpers. This truck pulls one of the R model pumpers to shows. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76131-mack-faw5371-12000-steer-axle-bearings-and-seal/#findComment-585639 Share on other sites More sharing options...
Vladislav Posted 2 hours ago Share Posted 2 hours ago Outer bearings are 45280/45220 (set 413 as mentioned above) Inners are HM212049/HM212011 (set 409) Stemco seal either 383-0139 or 383-0239. There's a wear ring of 4" OD the seal works against of but you don't need refreshing it if use unified Stemco seals.
