1998 Proportioning Valve

[Salonika]

Anyone have a good source for a new proportioning valve? I see some on eBay but I’d rather source from a reliable certified retailer.

Do you mean the one in front of the rear axle? Or the load sensing valve?

In front of rear axle.

I have never known of a failure with them.

So the seals inside must go bad eventually…..I mean mine is 24 years old. They have that lever with the spring attached to the body, that moves a piston / plunger inside the valve body, it must have similar characteristics to a master cylinder. Eventually it will fail when the seals inside fail. One of those seals prevents leakage to the outside since it’s the plunger that moves depending on cargo load……
