Technical Wiper bounce mk2b

markdarbypearson · Mar 27, 2020

My 2004 mk2b passenger wiper was occasionally banging the scuttle. I moved it up on the spindle but it still bangs intermittently and goes past home an inch and "bounces" back an inch. The hole in the nylon Bush doesn't seem worn oval. Any ideas?

Lift both wiper arms off the screen until they lock

Move them left to right..

Should be very little movement

Is one giving a lot more movement ?

markdarbypearson · Mar 27, 2020

No movement on both.

I'm still a bit baffled after reading through the threads!
linkages or grease in motor?? seems odd its just passenger side?
Any ideas would be most welcome!

No movement. Linkages/motor grease? Seems odd it's only passenger side?

If there is no slack detected at the wiper pivot..
I cannot really see how it is flailing around..

The assembly is tight in its mounts..?

I'll have to check. You mean the whole thing and how its bolted/mounted?

Yes..

From memory.. its in a Tubular Frame..

3 or 4 bolts hold it into the scuttle

Wriggle the 2 flat strip arms while you are there.. thats where the bulk of wear occurrs

Tried to send video on here but won't let me. I wiggled the blades and they are slack anti clockwise and clockwise. Passenger side much worse. Is that simply the nut on top of the spindle? Can I send you the video another way?

varesecrazy · Mar 30, 2020

Dont bother with a video..

What blades?

You told me the wiper arms had not got any free play.. so whete is this movement?

nitramtpr · Mar 30, 2020

You may need a new wiper moter (try the clips that I said about in my post about the alternator). There's a guide about it:

Link to ebay for the motor:

Meant arms sorry. Now I've lifted the blades off the windscreen there is play anticlockwise and clockwise. Had a look at the linkage first point of connection and the clip and joint is loose allowing the twist play. Pass side is looser

Try these clips:

They'll hold them on tighter. Worked for me. Quite tight and fiddly to fit but they'll go on eventually.

I noticed on the ebay pic there's a rubber washer under the clip in situ. There isn't one on my linkage. Is that correct?

nitramtpr · Mar 30, 2020

The rubber washer is in the wiper arm linkage and creates a buffer between the linkage and the motor part.

nitramtpr · Mar 30, 2020

There's a compnay (Wipex) that do replacement linkages, if you look at the picture you'll see the rubber washer in the end:
