Windscreen Wiper Arm Replacement

**LRD414** · 22nd February 2016, 04:22 PM

I have just replaced the driver side windscreen wiper arm (not blade).
It is a reasonably straightforward job but I thought I'd put up a few details for future use anyway. I've only seen information on changing the blades.

Part Numbers:
Driver Side - LR038123 or DKB500040PMD
I ordered using the LR number but package had the DKB number on the sticker. No issues with fitting so I think they're interchangeable.
Passenger Side - LR038119 (I didn't change this one)

I needed to change the arm after it got slightly bent during a minor incident on the Cape last year. Refer post #20 here (last on page):
http://www.aulro.com/afvb/queensland-reports/224345-cape-york-outback-qld-2015-a-2.html

It was still operational but made a loud knocking noise at the top of the blade's stroke.
This noise is more common in units where the spring tensioner has become weak but I thought a change might also cure the noise if caused by a slight misalignment of the arm.

You can see where the original arm is quite twisted when compared to the new one in this photo.

Sourced a genuine arm on eBay from the UK for $74 delivered (plenty available but watch the total cost when shipping is included).

Sourced an arm changing tool from SCA for $30 delivered (couldn't get in a store for some reason).

Be aware that it is not a good fit to the D4 wiper arm but still works.

This cap lifts straight off with a small screwdriver.

Note that the threaded rod of the tool is not centred on the mechanism shaft so I re-installed the nut loosely so that the tool had something to work against.

It was more difficult to release the blade cartridge than I expected. It required some force while holding down the little locking tab.

And the best part .... silent operation once all put back together.

Regards,
Scott

EDIT: just for reference, here is a useful thread on replacement wiper blades. Although some of the later post do lower the tone a little ....

Great info, wish I had found this previously! I was searching Bunnings yesterday to find a tool to do this removal and they had nothing really suitable. Good to see that a purpose built tool exists.

The Toledo Wiper Arm removal tool is available at VEK Tools (https://www.vektools.com.au/toledo-w...oval-tool.html) who have shops at the following locations in Sydney. I'll be ringing them tomorrow to see if they have one at McGraths Hill.

3/50 Cumberland HWY, Smithfield
6/4 George Hunter Drive, Narellan
23/5B Curtis Rd,McGraths Hill
6/2 Ash Rd Prestons

Slightly off topic ..... Sorry Scott....

I recently got quoted ~$275 for my front blades to be replaced......OMG!!!

I saw an American dude on you-tube change the blade assembly. A D3, but I assume it's the same on a D4. Looks a bit finicky but straight forward enough, though I image they will be pretty tight first time. So I'm going to give it a shot.

Anybody got ideas on where to get the blade assemblies? There are plenty online but I figured someone here would have experience and guidance on where to buy. I also noticed some non-genuine ones, wonder if they are any good?

Cheers.

Kev.

Kev, the thread I linked in the 1st post has good recommendations for blades.

Thanks mate. Got taken off course by your bent arm.

Here's a link to the Bosch site. These have been recommended here before. I bought a set a couple of months ago and they are good so far. The hardest one to change is the rear window. The front ones are really quite easy when you understand what you're doing. Make sure you don't drop the arm onto the screen

Hey Scott,
Do you really need the tool to remove the arm? Can you use a trim tool to pry it off instead?

I buy the Bosch aerotwin blades from windscreen O'brien, they are cheaper than ebay,

Despite what their catalogue says, both drivers and passenger sides take the 530mm blades without touching each other, making for maximum cleaned area, and smooth silent windscreen wipers. I love em. Changing is dead easy, haven't changed the arms, no need to. They last about 6-8months, but I'd rather have a clear windscreen....

I had the Bosch and I found they didn’t clean the screen well,particularly on the drivers side.

Picked up a set from autobarn,Cant remember the brand,about $19 each and they went for ages.

I switched back to Bosch after trying Wipertech and not finding them good for me.
