    Is it safe to assume there is a bushing that fit into the linkage arm and then snaps onto the motor shafts stud?

    Are these bushings available????

    Or something else?

    the linkage popped off the motor's arm...all I could find in the sump was dirt , crust and a couple pieces of a yellowed plastic thing......1981 Diplomat

    Anyone have a temporary fix idea?

    Thanks!

    Well I bought them ....

    In the process I found that the drivers side one os also missing....managed to press them into the linkage arms....but cannot seem to get them to stay on the shaft of the motor or the drivers side assembly...turn the wipers on and they work for a wipe or two and then they pop off......

    My next thought is to remove the whole assembly from the cowl, including the nut off the motor to try and press them onto the studs better......

    Seems like they would just pop on without going through that though.... ??????

    Those can be tough to get on all the way, especially with replacement Dorman bushings from China. The plastic is almost too hard and you may have to use a pair of channel locks to squeeze them together. At least that's been my experience.

    Yes, the mopar bushings last longer 3799089 IIRC. I use a c clamp and a socket to press them on. And yes out of the car is easier. My guess is you don`t have it snapped on all the way.

    I had a heck of a time getting mine together and it was all replaced with NOS linkage and pivots. Like 77 said, assemble it out of the car and then sneak it in through the cowl openings.

    Excellent idea. That would help assembly a lot.

    I have done dozens of these, and I'll tell you, use the factory bushings. Much more money, then the Dorman, but worth the money. They are still available from the dealer. Just did a 79 Volare, yesterday.
    PS: If doing one, do all of them and as was stated remove the motor arm, linkage, and wiper pivots, do it on the bench, and reinstall the complete assy in the car.

    Well, I had to get them working ASAP so I did end up using the Dormans for now.....I will probably try and get the OEMs from the dealer and have them on hand.....

    The Dormans went together OK....though they were tight.....

    Any chance you have dealer part numbers for them?

    They are not as cheap as aftermarket but don't over pay. Rockauto has them, also E-bay prices are all over the place on E-bay. Also still available from Crhysler. I would guess not to pay more then $7.00 each. Four required per vehicle.

    PS: make sure you clean the rust off the pins, before installing the new bushings.

    In a lot of cases, paying more for genuine parts is cheaper in the long run. If they cost less but you have to replace them every year or two, are they really cheaper? Not to mention either your labor, or paying someone else's labor charge. At work, there are certain parts we use ONLY genuine parts from the dealer. The price is higher most times (sometime's the price is the same as A/M) but we do so because the aftermarket parts either just plain don't fit or they're known for premature failure (or junk right out of the box). Plus, when it's Mopar parts, we get to see the cute 20 something redhead that runs the local Dodge dealers delivery van;)

    Using a small bit of grease (not much) helps with instillation and makes them a tad bit quieter (on the pin portion, not the link portion). Boiling them helps with installing them onto the links.

    The OEM dealer bushing, come with grease in them. Also, I have never had to "boil" the OEM bushings. "Dorman" brand, and "Help" brand, are a pain to install, and don't last near as long as OEM parts.

    This seems to come up a lot, it would be nice if there was a technical thread on wiper motors arms bushings etc. and how to overhaul the assembly and what parts to use.
