- This old Yamaha G2 golf cart from the mid 1980’s had a clunky front suspension, as a result of failing wheel bearings and eroded king pins and king pin bushings.
This video is a fastener by fastener description of how to replace king pins and king pin bushings. The kit we used was made by Excaliber, STR-023, which on the label is said to be appropriate for Yamaha golf cart models G2, G3, G4, G5, G6, G7, G8, G9, G10, G11, G12, G13, G14, G15, G16, G17, G18, to G19. A similar kit is available on Amazon, and from other retailers. To determine your version, search for the vehicle serial number and then use a search engine to find websites that describe model names. From there you may be able to find a parts list and service manual.

This video saved me time, money, and frustration. Thank you!!!
Just did the king pins on an old G2 that I lifted with 6" A arms and some custom made brackets with longer coil over shocks. They are durable carts !
Great video , Just started the yamaha G-9 , almost done! the drivers side spindle was a bear to disassembly, due to the negelct of riding on a bad bearing for too long The passanger side was a piece of cake . Thanks for posting , I always look for the best video before starting a project Thanks again!
Exquisitely executed tutorial! I mostly deal with club car and ez go. I now have the confidence to tackle a yamerhammer
I watch your videos all the time, thanks for dropping by!
@@spelunkerd ericthecarguy turned me on to your channel years ago
Thank you saved me a lot of wondering what to do on my first time Golf cart repair A+++++ video
Love the way you say not as nearly as loose while it's looking pretty much the same amount play as it did in the fist place 😁 the missing washer didn't help that's for sure 🤦
Cool
Nice repair :-D, the right tools make the task less of a struggle.
I have struggled with the wrong tools.
No fun :-(
I was thinking about you the other day, when we were visiting my daughter in the UK. I see your thoughtful remarks in many channels we follow together. Cheers!
@@spelunkerd Thank you, I do try to leave a decent comment, but my depression and other problems tend to upset my mood too often.
I think i need a new brain lol :-D
Keep repairing :-D
@@spelunkerd Most of the things i watch are repairing based, as i have spent years repairing electronics, its more interesting watching mechanical repairs now.
Sorry long waffling :-(
Very nice job .. should outlast the cart by far !👍👍
Is the hole in the bottom side of the arm worn out? Seems odd that the bushing hat slid in loosely, then you still had play in the knuckle with the new king pin.
Good question, I think the entire knuckle needs to be replaced because that opening is wallowed out. However it is working now and for such an old cart, the owner is happy it is still running and steering fine. In a licensed car this would not be an acceptable repair but for what it is used for, on private land at slow speeds, I don't see a problem. At this stage, with a vehicle that is almost 40 years old it might be hard to source parts, probably the junk yard would be the best bet. I'll throw out a guess that in the past, the bushing wasn't replaced soon enough and the kingpin wore into the knuckle itself. There wasn't a whole lot of wear on the bushings I removed so I think it happened years ago.
Hey again I completed one side when doing the other side canvi leave the one tire on when changing the other side
Sure, no problem to do one side at a time.
Thanks buddy
Hey again i was just wondering if the kingpins r rusted in the bushings if i could just put a bottle jack under the kingpin once i have it already jacked up to press the kingpin out
Yeah, I suppose you could do that. It wasn't that big a deal when I did it, the brass doesn't tend to corrode much on cast iron. The movement of the cart tends to free up any significant corrosion over the years.
O ok yea I figured if I have any trouble I'll just get a block put the bottle jack under kingpin in press it out.thats only if I have problems just want to come up with a back up plan.thanks so much for always answering
Do you a lot of camber if the spindle still has play?
That's a good point, there will be more negative camber than it was designed for. These king pins seem to have a fair amount of slop out the gate, and camber is not adjustable. There is no evidence of excessive wear on the tires, and wear in these vehicles is mostly in years, not miles. Thanks for stopping by!
It doesn't look to bad like u ssid as long as the kingpin doesn't get stuck do u think i can do it without air hammer
No problem, an air hammer is not necessary. The king pin turns in the bushing when normally steering, so it won't be very stuck. If you hammer on the narrow end (bottom) you're less likely to flare the end, but in any case the risk of that is pretty small. Most air hammers are useless anyway.
Ok thanks alot
What do u mean by flare in out I have new kingpins but I'm going to keep the old ones like u said do
@@joshuarhodes9022 When you beat on the end of a piece of steel, the top of the steel can be mushroomed out which would make it difficult to get through the narrow opening. If you hit the tapered end, it can mushroom a little and not expand enough to limit movement. Some guys use a drift punch with a taper or ball head to try and avoid mushrooming the end of the steel.
Does it matter which way the split faces on the bushings
I don't think so. I'll throw out a guess the bushing may rotate a little until it finds a stable spot. I tried to avoid placing the split on the medial side.
Ok gotcha
Thanks
How long does this normally take sir for one side or both
A pro who does this every day could probably pull one side off in about 15 minutes, but we amateurs are slow! I think it took me about an hour per side, including the delay to set up the camera angles, lighting and audio. If the king pin were stuck in the bushings, it could be much longer, especially if you don't have access to a torch or air hammer.
Thanks for replying spelunkerd
What would u heat up if it gets stuck in the bushings I'm replacing mine on my g9 because they are really bad.i have a propane torch if u think that will work
I don't have a air hammer though
Very awkward job to do on your own. Its looks like it could be made much simpler given some thought. Sail Safe mate. Ant & Cid
Overall I like this kind of simplistic design, made of components that prove the test of time. I think the control arm bottom hole had wallowed out a little, producing a loose connection at the bottom even after replacing the bushing. That would not be acceptable in a car but for a golf cart it will last decades before needing replacement. Thanks for stopping by, Ant!
