Gen 3 Cab suspension.

How many miles does the truck have? I too had this issue when I bought my truck, its a 2013. Only thing I would do different is use torsion springs from a day cab rather than that rubber bushing junk torsion spring. The day cab has a solid metal piece, you'd still need two, but it won't give like that bushing does. Or at least that is what I found one guy with sleeper volvos doing, replacing with day cab torsion springs, he swears by them. You also want to replace the torque rod. When I got the torque rod, and two torsion springs it was about $376 I think. I changed all that myself out at my dads place. Use a bottle jack between the frame and the cab air bag to push the cab back upright when you install the new stuff.

 

I will say if you don't replace the cab shocks (probably should but if you don't), and you feel it bottoming out when you hit bumps, could also be the cab bushings, too. I am not really capable either. I am not mechanically inclined really much at all, if it weren't for my dad I would have been lost or taking it to a shop to have it done.

 

Cab length and weight makes a huge difference in ride. But, having good cab shocks and suspension shocks makes an even bigger difference. Once you get that thing sorted, it should be a really nice place to spend the day.

I caught a ride with one of our local drivers, yesterday. That day cab on worn out shocks was horrendous. I could feel the axles skittering over every bump. The driver was oblivious.

 

Ugh! That patchwork of concrete being called “roads” is ridiculous. But, you’ve got beautiful weather.

 

Just be careful jacking up the cab. The metal is thin and can bend really easily. I ended up using a whole bunch of lumber between the frame and the cab. I overinflated the bags a bit then stuck the wood under and let it down gently. Make sure the hood is up, because if you raise the cab too high it will rub the hood. At this point you can try to do your repairs, or you can fit a bottle jack underneath to get more clearance. In order to shift the cab back into position, I used a 2" ratchet strap but I don't remember where I hooked it. There are some videos online for replacing the cab air bags which might help.
