New member with EV version

FlynHam — Sat, 10 Jan 2026 22:07:56 +0000

Good afternoon all, New member here with a recently purchased EV version of the gopher, that has "issues."

If there's any interest here in the saga, I may start a new post with how we got to where we are now. Not sure what the future holds, but I have learned a decent amount about EV's in a short amount of time, but still SO much to learn.

Wobbly ride - Need help fixing!

RandomTask — Sun, 12 Oct 2025 07:17:49 +0000

I've been on the Go4 Facebook group, just started tinkering with my new-to-me Go4. I'm handy but pretty inexperienced as a mechanic. Have the front wheel jacked up so it's free spinning with jack stands on either side. Cleaned up under the hood and checked for loose bolts, everthing seems tight. I can't tell if the wheel bearings are looser than they should be since I'm not used to checking such things. Dashboard pulled off and most everything cleaned off, there's a metal piece in the front left under the dash that's bent up and broke off easily which seems pretty weird but probably not causing the wobble.

I'm told pulling the suspension apart, regreasing and retorquing should happen next. Is there a video that shows a similar process? Unsure of how to even get started down this road. I'd like to get new tires as soon as possible too - 175/70/R14 (Credit to Rick Lopez)

Thanks!

GO-4 fuel hose repair

walter — Fri, 18 Oct 2024 17:28:25 +0000

In the GO-4 Interceptor Owners Group Facebook group Birdie Lu’s Icecream Truck asked:

Good morning Go-4 group. I got a crack in the plastic fuel line that attaches to the back wall. Mechanic says they found a new one for $244.00. That seems high. I thought I would check here before I gave them the go- ahead. Picture for enjoyment. As always, any help is greatly appreciated!!

Answer: Go to the auto parts store and get Nylon Fuel Line Compression Unions. Get the right size for your fuel lines. Make sure they have the inserts that go into the fuel line to prevent the line from collapsing when you tighten the nuts.
