SERVICE PROCEDURE
Procedure A - Repair Rattle Noise
1. Partly open the retractable hard top as shown in Figure 2.
CAUTION:
When left in a partially open position the roof could slowly drop which may cause roof damage.
2. Check both 0-rings for impressions.
^ If impressions are found on either 0-ring, replace both 0-rings with a suitable tool (see Figure 2 & 3).
^ There is one (1) 0-ring at each rear corner of the center roof panel mounted on center roof panel pins.
3. Next, loosen the Torx screws for both rear roof panel retainers (see Figure 5).
^ The retainers are located at both front corners of the rear roof panel.
^ Loosen the retainers enough so they move around easily by hand but not on their own.
^ Torx screw size: T-30
4. Fully close the retractable hard top.
^ This will allow the retainers to align with the pins.
5. Open the retractable hard top and then tighten the retainer's Torx screws.
^ Torx screws torque: 9.5 Nm (0.97 kg-m, 84 in lb)
6. Road test verify repairs.
Procedure B - Repair Rubbing / Creaking Noise
1. Partly open the retractable hard top as shown in Figure 6.
CAUTION:
When left in a partially open position the roof could slowly drop which may cause roof damage.
2. Using a damp cloth clean the contact surfaces of all retractable hard top related weather-strips (see Figure 7).
^ Also clean the area of the seal (where circled in Figure 7 and 8) on both sides of the vehicle.
3. Using your finger apply a thin coat of DuPont Krytox(R) Lubricant (see PARTS INFORMATION) on all cleaned weather-strip contact surfaces.
^ Make sure to apply lubricant on both surfaces of seals with two (2) contact surfaces. See Figure 9 for example.
^ For cleanliness it is recommended to use latex or similar type gloves.
