    Strut Piston Comes Off

    In break down of the magnetic struts of a 2003 Seville, should the strut piston be able to come completely out? Doesn't seem right to me. And I don't think it is good to find a lightweight gritty grease leaking everywhere, about a 1/4 of a cup all together at the most.

    Re: Strut Piston Comes Off

    Pictures would be interesting to see. I would conclude the piston should never come out. It's rather hard to believe. I am not privy to the consistancy of the specialty fluid use in the Magride dampners but if the piston comes out I would suspect serious damage in that strut/shock.

    Re: Strut Piston Comes Off

    I agree, it is making an awful banging thumping clunking noise. Especially since I took it off, to replace the upper mount, hoping to fix the racket, instead its much worse.

    Looks like I will be tearing it all down and replacing the strut this week.

    Anybody have a link to the step by step? I'm not certain I put the upper mount on correctly, the piece that alters the angle of the top of the strut.

    Re: Strut Piston Comes Off

    You NEED a real GM/Helm service manual or a subscription to www.alldatadiy.com.

    ANY fluid leaking from an F55 strut is cause for replacement
    - and I would strongly suggest you replace BOTH front struts - if one is excessively worn, so is the other.

    Replace both upper strut bearings, too.

    Talk to Chris in Parts at Rippy Cadillac over there >>>>>>>>>>

    At 48K miles and 500$? I'll take my chances replacing one.

    Re: Strut Piston Comes Off

    Ugh, why did you have to say "ANY" fluid, because there is a bit at the seal of the passenger side.

    I am definately getting the impression the car has hit something substantial at the front drivers side.
    I have discovered since buying it:
    Busted Strut
    Bent Wheel with a pin hole leak
    New tie rod end
    Missing nut on the transmission/cradle mount bolt (the one behind the drivers side strut)

    I incorrectly guessed the clunking was the steering shaft during our test drive, didn't see any fluid until lifting the boot up on the strut, while poking around there notice a non-factory tie rod end, meanwhile, a tire kept losing air though a suspected nail, plugged, still leaked, put in water tank, find hole in wheel, and it all starts to add up now.

    Having said/discovered all this, what more should I be looking for?

    Is there evidence of a recent history collision repair? Many times collision repairs neglect to address damage not visible only to be realized after ill tire wear becomes present and chassis damage is revealed.

    Whatever - You're trying to maintain a $58,000 car on the cheap. $1,000 for suspension parts is peanuts on the scale of things...............

    BUT the evidence of right front steering and suspension parts replacement is not good - not good at all. Start snooping for missing body rivets, plastic rivets, odd welds, plastic liners and pieces.

    No, mine was 10K$ car. so spending 10% is a bit different on my scale. I do want to replace it right, but I'd like to do it with out eating Ramen for 3 months straight.

    And I am finding a bunch of the odd plastic rivets. My concern is more unfixable items, bent frame/body.

    Should the body mounts have a loose piece in them? I thought about tightening them up to spec. (if they aren't) But thought the loose middle section might be some sort of absorbtion material.

    Yes, but a different strut. The bottom of the piston was straight cut, no nut no nothing.

    Re: Strut Piston Comes Off

    Look at that!
    It looks like bottoming out damage although I suppose it may have just been defective and came apert inside there.

    That is not the piston, its the rod the piston is fastened too.

    Does it look broken on the end?
    You want to restore the Magride it is a trick option that was only common to the Corvette when introduced.

    Other way around , j k, .......the 2002.5 - 2003 STS (Seville) was the F55 Magnetic Ride Control test mule. Corvette got it late in the 2003 model year.

    No, it did not look broken. Just covered in the gritty grease. I am letting this be my confirmation the clunking noise is in fact the strut...

    I am replacing it with a new Magnaride strut, I just can't afford to both right now. I'll see how it goes once I get the new one to determine how quickly I replace the other side.
