I have found that the shackles are ripping out of the bolts on my tri-axle 2011 Cyclone HD 3950.there is approx. 75,000 miles on my camper. I understand this is normal wear and tear? What is the go to "kit" for complete replacement with wet bolts / bushings and heavy duty shackles? I have an 8 hour trek to embark on in a week and a half so I need to get under way lol. Thanks in advance I would really appreciate anyone's help that has been here before.
