Shock Replacement Time?
Hey guys, I have a question on shocks specific to Motorhomes.
I tried to locate a recent thread on shocks, but the only ones I found were about a year old.
I have been unable to locate the replacement of any of the shocks in the maintenance history of the 1987 345, so at 16 years and 72,000 miles I suspect that it is about time.
I can set up a rocking (rolling) cycle by utilizing the entranceway step, two or three load cycles establishes a movement of about one half inch measured at the step bottom. The roll cycle will then continue for about four more cycles before no movement is discernable.
Is this continued rolling movement (4 cycles) serious enough to indicate worn shocks, and,
After I have the first shock off, what would an “unacceptable for further duty” test be?
I know the amount of work and time I am looking at, it would make no sense at all to go back on with an old shock, but I was just wondering if there is a rule of thumb for a P-30 type of shock that would indicate excessive wear, say 1” of immediate movement with a 100 pound force applied?
Anyone have any sources for (or thoughts on) a good Bilstein shock for the rear (tag axel) suspension, or an experienced based suggestion for the front spring assisted shocks?
