    PANTHER LEAN ISSUE TSB Crown Vic, Grand Marquis TSB 93-1-1

    TSB Found on previous models LEAN ISSUE --

    Two of my four panthers have "the lean" and two don't. The two that lean ALSO SIT 1.5 to 2 inches taller in front and EACH ONLY HAS 30.000 miles. Drives me fricken Batty!

    Wild thing is... Of the two that sit high in front AND lean, one is a Marauder, and the other is a CVSPORT.

    I found NOS (rare) Heavy duty front springs with same stock tag codes as Marauder.... Installed them with new Heavy Duty Shocks...AND THE DAMN CAR STILL SAT 2 INCHES TOO HIGH. So I uninstalled them and had 1 coil could cut... And it sits almost exactly like the two stock panthers do.

    So I then installed new rear KYB struts, and A-2220 Heavy duty airbags (Limo etc).

    The new KYB shocks were installed a while back with new rear sway bar, so I just installed the new heavy duty airbags and they are BADASS. Could feel the difference in the driveway. The comparison is as striking and when you first installed New Metco Watts link and control arms....That much of an immediate noticeable difference. Car now sits 2 inches above rubber both front and back like my other two stock Panthers.. Looks amazing.

    Bad news is... Car still leans a little. It is not the bags, not the shocks, and not the springs. 1 owner car, never wrecked, still near showroom. Mechanic checked everything he could think of.

    SO I SEARCHED AROUND THE INTERNET AND FOUND THIS OLD TSB.. 93-1-1

    2” above the rubber and looks amazing should not be used in the same sentence.

    For some reason I thought this thread was going to be about air/fuel ratios. You know like "That Panthers running lean, man."

    It was an honor to have
    my ASS kicked by you!

    In reading the full TSB, they actually had kits made withseven 1/2 "spacer" bolts for the low side. It was a great read!

    Part of the TSB discussed how to "settle" a car for measurement tomake sure the car qualifies for the fix.

    Not making this up... It has the dealer load trunk until rear height adjusts,unload trunk, and then shake car up and down in rear, shake up and down infront, and rock car side to side, right above front/rear door pillars. Then,After the procedure to measure (on flat ground) to lower lip of wheel well.

    So I've already shared the above suspension and bag replacement... (Sadly) Notcuring my "lean."

    A week later I was in Downtown Sac, where the roads have a heavy crown intogutter (we are a 3 river city... lots of rain/water/flooding), on one waystreet parked with my passenger side 12-14 inches lower than driver's side(hard to open driver's door). Parked for an hour, came out and remembered theTSB. Just for fun, I rocked car side to side as described in the TSB, using thecrowned road to gain more leverage/movement.

    People were walking by, casting odd looks my way, so I stopped. Then I thought,heck with them, the conditions are too perfect, so I went back at it like I wastrying to rock and tip the car over (harder since all new suspension parts wereinstalled front and rear). And I seriously rocked the car for a few minutes.

    Got in, drove home, made some tight hard turns, hit freeway for 5 miles, and NOJOKE. MY CAR LEAN IS NOW NON EXISTENT. It has been three weeks now -- and I amsure I will get flamed...but I am going to do this every time I notice thelean.

    Someone else please try it! I understand that this shouldn't work... BUT underthat same premise our cars shouldn't lean in the first place!

    Post up if it helps!

    I noticed about 3 months ago that my marauder started leaning to the driver side. Not sure why as I hadn't had time to investigate it but it has not corrected itself so I assumed it was bad / failing bag on the driver rear. However, the pump does not run any more than it did when new so that threw me off a bit as well. I will check out the tsb's when I get some free time and post back with my findings.
