B61 Front Suspension Help Needed!

Recommended Posts

Hello All,

I need some info. on my B61 Mack. I am new to the Mack world and this is my first truck.

The front end has a ball-joint arm on both sides of the frame that do not appear to go anywhere. I think I am missing something but cannot find any literature on it.

Can someone help guide me to what I am missing and what parts I need to correct this problem?

Attached are pictures of the arm.

Thanks, All

Dan.

not many of those survived,basically just a steel rod with a ball joint on each end,an early type of shock absorber,the bottom would attach to front axle.

That is a shock and there is a link that is missing that goes down to a braket on the axle.

those are shock absorbers the connecting rods would have connected to a hanger on top of the front springs .someone else will likely know where to find the rods or have more info than i do

One of mine popped loose at the upper ball socket, fell and bent around the axle. Ugh. I removed both sides and replaced them with all thread and heim ends. If I recall the holes are 9/16" in the mount, but I used 1/2" heim ends and bolts. Been about 7 yrs? and no problems yet.

I could have made spacers to make them fit snug, but I can't see any issue with them working loose. Not that the front axle moves that much anyway.

Thank you all for the input. Now at least I know what I am looking for and where to attach them when I replace the link and ball end connection on axle. The shocks themselves still seem to work. Just no link of connection to the axle.

Do I really need them? I will only be hauling a 40 foot flat bed with antique tractors weighing no more that 12,000 lbs. Short distances at low speeds.

I don't want to spend a lot of time and money on something that I don't really need. Thoughts?

I only hooked mine up to make the truck look more original underneath and I had to make a couple of the rods.

All any shocks job is to dampen the suspension bounce (or recoil). In my personal opinion with the normal B Model front springs and normal tires they are pointless. Paul

You will likely never know if they are hooked up and working or not there at all.

I suppose if you actually loaded the front axle really heavy then they might actually help control the spring. With the minimal weight up front, the springs never moves enough to worry about it.

Maybe heavier oil could make a difference?

Not one bit of difference. The different weight oils require different damping valve settings, so one cancels out the other. Plus you get more tire deflection than spring movement in normal conditions with the early suspension like on the B. Paul
