My wiper arms crapped out today so I bought the replacement bushings. The problem is THOSE LITTLE ARE HARD TO POP IN!

The one on the driver's side is under the cowl and I just can't seem to get at it to pop it in! It is not directly underneath the access hole and I just can;t seem to be able to get at it to pop it place.

PLEASE - any hints? I am so tempted to "enlarge" the access hole

Take all the linkage out of the cowl, replace bushings on bench, then re-install.

DITTO - replace them all while you are at it. Use a little lithium grease and push them on with a "c" clamp.

ouchman where did you find the bushings? It has flooded the last two days here and last night I found my noise, the bushings fixing to fall out. Thanks.

HELP! part # 49440 - most auto supply stores

Trooperthorn

Yep, take out the linkeage. Dont forget the greese. The first set I did, I forgot the greese and didn't reaize it until I turned them on and they squeaked. 6 years later, they still squeaked.

DOH!
Sometimes the obvious just isn't obvious to me!

Thanks for the help.

Thanks ouchman. I see your a fellow Lonestar State 1st genner. I'll check the parts stores today. Appreciate the help.

channel lock pliers are your friend

Ditto. (And that is the tool recommended for this job in the FSM.)

Also see the following old post:

Bill Gilbert provides the NAPA part numbers as well as complete instructions to complete the job. In addition to the channel locks, I used a small socket with some lithum grease to drive one of the new bushings into the steel linkage bar (on the workbench).

on my '76 i put a small socket over the bushing and used the linkage and a pair of pliers to pop em in place. Dont know if its the exact setup in our first gen trucks but it should be similar.

Job done!

Easy Breezy when they are OUT of the truck. Ample grease applied to bushings - runs smooth as a Baby's Backside! Better than it EVER was before!

THANK YOU

I know that for the older cars, you can buy a kit to add a grease fitting to the pivot as well... dont know if that would work on these trucks too or not... just a thought

After only six years, my wipers failed in a rainstorm and I have again replaced all four of my plastic bushings. I’m convinced the demise of the most recent bushings was hastened by the lithium grease I was using. This time I utilized pharmaceutical grade petroleum jelly (“Vaseline”) – hopefully I’ll see a little longer life from this set.

Some, if not all plastic bushings are designed to run dry. I know that in trailer spring applications, if you grease the bushings in the rockers and spring ends, they'll wear through in a hear because the grease captures road dust and dirt and makes an efficient grinding compound out of it. Installed dry they last a long time.

There are dry silicone lubes, usually applied with a spray can, that give you the best of both worlds.
