Pulsation Dampener Service
Is there anything to rebuild in a pulsation dampener like the valves? I've had some light bouncing in the car without any errors or warnings and I suspect its this. I purchased a new bulb to put on and I can see that there are a couple places you can put a wrench on the body, but I don't want to start pulling it apart blind. I'd like to change whatever o-rings are in it while I've got the system apart changing leaky hoses.

There are four air cells in the suspension system , the ones known as "accumulators" are the ones which can cause a bouncy ride
the one called a pulsation damper doesn't affect the ride , it's to reduce vibration and noise
the front and rear accumulators (You need two) is: A220-327-01-15
Be advised there are two other nitrogen spheres in the system as well. One is mounted to the pressure relief valve (Part #A220-327-02-15) which is found in the front right side of the vehicle.
The other is a small nitrogen chamber (Called an Air Cell) that sits near the fuel pump in the driver side mid/center of the vehicle, (Part #A220-320-04-15).

This is the part that I've been incorrectly calling the pulsation dampener. I have a new sphere on order but I'm wondering if the pressure relief valve itself (Part #220-320-08-58) can be rebuilt in a similar fashion as the two main valve blocks. I've seen the threads on rebuilding the main valve blocks, but not this pressure relief valve. I just don't want to take the thing apart and risk ruining it for nothing.

Again , the pressure relief valve , and the sphere attached to it, are to reduce noise and vibration .if you had no problems with a humming noise or vibration you don't need to touch that valve
if you are getting a bouncy ride , it's much more likely to be the two accumulator spheres which are responsible for bouncy ride

I've got the accumulators on order too but I've always heard that they don't reduce bounce either; just take the strain of pressure spikes on bumps. Either way I'm replacing all three, so I'm hopefully the problem will be solved.

if you are doing everything do all 4 spheres , I listed the part numbers and location above
