Remove Wiper System

Need to take the wiper motor and drive and arms all off the bulkhead. Where to start? Can't find this in any of the workshop manuals I have.

Remove wiper arms first!

Instructions in order below, call if you get hung up on anything.


Instrument cowl off, upper dash off, lower left cover (wiper motor cover) off, wiper motor unplugged, remove wiper motor strap (note orientation of nut-plate so that it clears the support ridge hidden in the bulkhead), unscrew wiper motor from cable tube and withdraw the cable and motor (use gloves and a plastic bag to get hold of the greased cable), remove the two small nuts from the back of the wiper arm wheel boxes and remove the connecting tubes and end tube, remove the wiper ferrules, remove the rubber covers, unbolt the wiper wheel boxes from the front (13mm i think) and draw the wheel boxes into the truck to remove.

Installation is the reverse of the above unless you are converting to TD5/TDCI type arms.

Have fun!

Can't get wiper motor and cable undone unless I pull wiper motor apart.

The wiper arms come off the splined nut at end, so I'm not sure why I would even need the small hex bolt to hold that splined nut on the end. Either way, I have four different types of hex wrenches, but not one of them fits that hex bolt. It seems to be 2.25. I have 2.5 and 2.....

I can't figure how to get cable out of wheel boxes, even with the back plate unbolted, the front plate is shaped in such a way as to hold the cable in place -- does it draw out from end?

Like Brian, I typically pull the drive cable with the motor together and reinstall the same way. Take the wiper arms off so there is no resistance and pull the motor/cable through. The wheel boxes will spin as the cable pulls through so be slow and methodical. Removing the tube and wheel boxes is pretty easy as long as the splined hub comes off the wiper shaft.

Since I'm an idiot, and don't know the names of anything that I'm talking about, I'll use pictures so you can help me.

First one shows the wiper arm shaft. I cannot remove the splined mount nut whatever thing the wiper arm actually slides onto. It is lose, even spins freely, but won't come off.

Its just a force fit. I have had to cut them off before due to rust but the shaft it fits on simply has a flat side and the set screw is meant to lock it to that flat so it locks to the shaft. If you have the splined collar spinning on that shaft the sucker should pull off.

That's why I don't understand why these are doing this. I figured it was either a groove, or a flat side.

Why do I need to take the back of the wheel boxes off? All the manuals say to do this, but even if I do, I can't get the cable off. It looks as if you have to draw the cable all the way through, but I'm not able to get it to budge, don't want to put too much force on it.

Yes the cable draws through. I don't remove the back of the wheel box's, as you say kind of pointless.

Have you removed the clamp on the curved part of the tube where the wiper motor clamps to the guide tube ?

It sounds like your wheel box's may be locked up with rust or were they working before you started teardown ?

Getting the cable out is independent of getting the splined hub off of the wheel box shaft.

FWIW wheel box's are sub $50 and sometimes a cutoff wheel makes more sense than spending hours wrestling a worn out one.

Yeah, thanks. I'll see if my other set can be removed, order new if I need to.

Wish simple jobs like this didn't waste so much of my time. People always ask why I can't get my Rovers up and running.... this is why.

Get out the torch (carefully) and some penetrant - make a small screw puller if needed - but Doug is correct that the process is sometimes much easier if you order new parts and resign yourself to cutting them off to save time.
