Full Floater Posted August 26, 2015 Share Posted August 26, 2015 Hey. I have a 79 RS600l. It is a low mileage truck and has never had any suspension/bushing work done. I don't know camelbacks well at all. But what im noticing is that after turning a corner and parking; the axles dog track a bit. The front drive axle seems to go one way or another more so then the back but its hard to tell. Then it seems to straighten out going down the road. Is this at all ''normal''? Do I have something that is severely worn out? Quote Link to comment https://www.bigmacktrucks.com/topic/41527-camelback-dog-tracking/ Share on other sites More sharing options...
mrsmackpaul Posted August 26, 2015 Share Posted August 26, 2015 mate I feel from what you describe thats normal Paul Quote Link to comment https://www.bigmacktrucks.com/topic/41527-camelback-dog-tracking/#findComment-301622 Share on other sites More sharing options...
j hancock Posted August 26, 2015 Share Posted August 26, 2015 If everything seems to straighten out after the curve, it is normal. Mack used rubber mounted trunnion as well as brass but both utilized rubber at the axle to spring mount so there is movement in corners. 1 Quote JimIt doesn't cost anything to pay attention.

Full Floater Posted August 27, 2015 Author Share Posted August 27, 2015 Well that's sure great to hear. I thought for sure I had a $5k + shop bill in my near future to have some bushings done.

carlotpilot Posted August 27, 2015 Share Posted August 27, 2015 to add paul`s post every one new or old that i have driven moved around some. when they track out 3 or4 inches on a straight run then look for a problem 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41527-camelback-dog-tracking/#findComment-301677 Share on other sites More sharing options...
Full Floater Posted August 27, 2015 Author Share Posted August 27, 2015 And would that usually be a worn bushing issue? Quote Link to comment https://www.bigmacktrucks.com/topic/41527-camelback-dog-tracking/#findComment-301679 Share on other sites More sharing options...

RAYMAC Posted August 27, 2015 Share Posted August 27, 2015 yer used to drive a 1972 r 600 carting logs back wheels would come out a full tyre width when cornering good in the mud never caused any dramas we used to call it walk about suspension passed regerstration every year no problem 4 the six years I drove it so I don't think u have a lot to b concerned about regards ray 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41527-camelback-dog-tracking/#findComment-301684 Share on other sites More sharing options...
kscarbel2 Posted August 27, 2015 Share Posted August 27, 2015 It does sound like you are speaking of the Mack bogie's self-steering design capability (which results in reduced tire wear).Having said that, and assuming that you have rubber trunnion bushings, they could be in bad shape simply because they're 36 years old. Rubber deteriorates over time.......low mileage doesn't matter.. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/41527-camelback-dog-tracking/#findComment-301685 Share on other sites More sharing options...
MACKS Posted August 27, 2015 Share Posted August 27, 2015 Well that's sure great to hear. I thought for sure I had a $5k + shop bill in my near future to have some bushings done.It depends on how much there moving,if there walking out just turning a normal corner im thinking you need work done especially if you have brass.
