Norway Posted May 5, 2013 Share Posted May 5, 2013 Relpacing the crossmenber shaft or tube is a big deal.It has the be cut out and a new one pressed in if I recall correctly. Good truck spring shops can do the job. Quote Link to comment https://www.bigmacktrucks.com/topic/31054-camelback-life-span/#findComment-181893 Share on other sites More sharing options...

dds92780 Posted May 6, 2013 Share Posted May 6, 2013 I paid 800 for isolator bushings installed, and another 3800 for trunion bushings and new 44k spring packs installed. so about 5000 Quote Slow and Steady Wins the Race!

dds92780 Posted May 27, 2013 Share Posted May 27, 2013 Does anyone know if there is a big weight difference between 34k 38k and 44k springs? I had mine replaced last year and i was told not to go from 44k to 34k and i dont know why. I kinda still want to swap them out for a lighter one but don't know if its a waste of time and money at this point. All i can see is that i would have had to get different u bolts.

rsb502 Posted May 30, 2013 Share Posted May 30, 2013 44k camel backs are great when you replace the isolators go with the urethane and you'll double the life if your offroad a lot. 1 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/31054-camelback-life-span/#findComment-185991 Share on other sites More sharing options...
220cummins Posted May 30, 2013 Share Posted May 30, 2013 Worst part of the job ubolts on springs need a torque of 1700lbs each. torque multiplier helps 20' bar works too.You're not kidding. I've made up brackets to hold them on the forks of a fork lift. They are way easier to torque "upside down" then to torque under the truck even with a 4:1 multiplier.

theakerstwo Posted May 31, 2013 Share Posted May 31, 2013 44k camel backs are great when you replace the isolators go with the urethane and you'll double the life if your offroad a lot.First time I replaced the rubbers on mine the spring shop used the rubber pads and they lasted 3 months so I take it back and ask him why he used rubber and his reply was its cheaper. They was torn up and I don't gross over any. So I took it home and my son replaced them with the uretain. They are 3 years or more and no problem.The rubber pads was made in china but he charged me mack prices.I found the uritrain on ebay for maybe 35.00 each.
