The steel end cap/cover plate on the valve body can come loose from the cycling of the accumulator pistons. IF caught early enough it can be fixed with some blue loctite and a inch pounds torque wrench before the plate gets bent up.

Otherwise Sonnax offers a fix in the form of a LINK new plate.

Of course if your going that far then you might as well do the accumulator piston sleeve kits as well and be done with it LINK .

02-03 has the black connector solenoid pack, if replacing it chrysler requires the CAM plate to be replaced as well.

Overall the RFE has proven to be a decent unit, plenty of them out there and most of the glitches have been found by now and remedied. Any retard with a heavy foot will find a weakness.
