Removing Driver from Sealed Cab

Hi; I am trying to remove the driver from a Mission 764 Sealed Cab for repair and am having no luck.. I have unscrewed the 4 screws on the driver and the speaker remains rock solid in place. What am I missing.

1. Remove the front cover.
2. Remove the four bushes that held it in place. Beneath them are crosshead screws.
3. Remove these screws, and the surround board they hold.
4. You can now see the bass speaker retaining screws. remove them and withdraw the speaker *carefully*. (A knife under the edge helps to get it going.) The wires are at the back mixed up with the damping wool.
5. The tweeter has its retaining screws under the rubber gasket stuck to it.
6. The connectors shoud slide off the lugs, but mine are pretty stiff. Careful with the tweeter's: mine pulled out the termnal completely, and I've had to replace the unit!

Craftsman 19.2v drill. What is process remove the chuck. The back side of it has 17mm dual flat spot. I tried 17mm open end thin bike wrench but I cannot get the chuck to unscrew. I need it off in order to...

Hi Charles! The chuck is fixed to the spindle by a bolt (with Ph2 or hex head), you can find the bolt head if you look directly into the chuck (with its jaws completely opened). You'll just need to fix the chuck (with your hand most probably), and unscrew that fixing bolt (might be with left-hand thread! - don't use excessive moment, first try it gently both ways). After removing the bolt you'll just need to gently tap the bottom of the chuck - through a piece of wood - with a hammer, to remove the chuck from the spindle. Gently is the key word - in order not to damage the chuck and ball bearings/gear set of the drill.
Below are 2 reference links from Craftsman and Sears Parts catalogue - may help you as well.

I have a 2002 BMW 530i. The floor mat on the driver's side gets soaked with water after heavy rain storms. What can cause this problem?

Hi odure,

I would suspect one of 2 problems. Either the vapor barrier behind the driver's door panel is not sealing well, or possibly a sunroof drain is clogged. Usually the vapor barrier is the most common cause. I would recommend removing the door panel and check to see if the barrier is fully sealed. Also when removing the panel, replace any clips that may break, or that may be missing the rubber grommet on them.

I need to know how to disassembly the instrument panel of f-150 1997


Disconnect the Ford's negative battery cable. Turn the truck's front wheels straight ahead and then lock the steering column. Remove the A-pillars' trim by removing the screw covers and then unscrewing the mounting fasteners.

Remove the center console if equipped by unfastening the nearby trim panels, prying off the shifter trim panel, disconnecting the shifter cable and unfastening the console. Remove the steering wheel, then unfasten and remove the steering column covers, starting with the lower cover.

Remove the instrument cluster. Unscrew and pry off the knee bolster with the aid of a flat-blade tool, then unscrew and remove the instrument cluster bezel in a similar way. Disconnect the electrical connectors, remove the cluster's mounting bolts and remove the cluster--you'll need to disconnect the gear position indicator on an automatic transmission.

Remove the glove box by opening the door, pressing on the sides of the compartment bin together, pulling the door down and removing the fasteners at the bottom. Remove the center brace cover, center bezel and upper finish panel by removing their fasteners or prying them off their clips.

Detach the end caps to the panel with a trim stick or flat-bladed tool, then detach the hood release by removing its screw. Pry off the scuff plates and kick panels from the door frame. Pry up the defrost grilles with the same flat tool.

Disconnect the steering column shaft. Disconnect the electrical connectors from the column's harness, detach the shift cable and transmission indicator cable if you have automatic transmission, remove the pinch bolt from the intermediate shaft coupler and separate the intermediate shaft from the steering shaft.

Disconnect all remaining electrical connectors to the panel and unbolt all fasteners for the panel around the top, left and right sides and the ends along with the brackets at the center. Lift and pull the panel away from the windshield with an assistant's help, disconnect all remaining connectors and carry the panel out the driver's door.

Good luck.

Replace driver side power mirror on 2003 ford crew cab f-150

Muth makes the signal mirrors for repalcing the glass in the mirror head. On the site, they have nice instructions you can use for removing the door panel, and getting the mirror off ( obviously stop at the removing the glass part, and just replace with the mirror head you already have ).

Enter the Make, MY, and model you have, and on the products page are the links to the PDF version of the instructions for download.

I bought replacement drivers for Mission 780 do I replace visible screws...does the cover plate come off?

Screws are hidden under the plastic plugs where the covers slot in. remove cover, then maybe use a pencil and fingers to prize out the rubber "holes". Once all four removed, unscrew the four screws visible. Carefully lift off baffle, note that tweeter will be attached to the baffle. You then have easy access to the driver, again another four screws holding that in. You may find erosion on the terminals.

Midrange faulty

I've had the same problem/s. A manufacturing fault with the original midrange drivers of all of my Mission 780's and 782 speakers. If you contact Mission through their website they will supply an updated style driver for about £45, I would recommend buying 2 because the other one will fail eventually, if like me you use them every day. All four failed within two years of each other.
