noises

[grimreaper615]

just picked up a 94 gl1500. I've noticed while cruzing i get a knocking/grinding noise from what feels like my feet. only while I'm barley coasting. will not make noise on throttle or fully off throttle. ive heard about the u-joints... hoping it would be that as opposed to something internal in the engine or gearbox. any thoughts or sugestions would be appreciated. thank you.

I think your diagnosis is correct. You should get that buzz at almost any speed during no load on the shaft.
At any speed have you slightly throttled & de-throttled several times to hear or feel that clunk?

yeah i felt it today trying to get a better idea of what's going on. if I lightly snap my wrist and let off it clunks once on the snap and once on the let off. its mainly around 50ish is when its the worst

On the center stand and in 1st gear you could rock the wheel with your other hand on the drive shaft tube.
Also could use a long screwdriver as a stethoscope and check various places on the tube while 'rocking the wheel'... says grandma.
U-joint is near the engine. Always the chance it's one of 2 splines going out & wobbling.

very good. i will try that tomorrow. and start looking for a new u joint and probably some swing arm tool it looks like ill need. i appreciateit very much. thank you. wouldnt happen to know if a reputable place to get some parts? lol

I have 2 spare Schwing-arms, could part with one. Doubt yours is bad.
My intention was to cut out & plate weld for wider car tire but both sides are rather tight interior wise.

[grimreaper615]

i doubt it. i can live with a dent or 2 in the tube. as long as its just cosmetic and not ground through the tube. 98k miles. I just want to get her back to road worthy. then start going through it.

Both tubes are untouched.

What you're describing is classic u-joint slop. Time to start planning to replace it.

[grimreaper615]

Would you know of anywhere I can get a new u joint? I don't wanna put old used in it. Local shop told be ball park 600 to 800 if I bring my parts

Honda, Mr.Cycles, Partzilla, etc.

Mr.Cycles usually has the best prices for OEM parts. $157
Check the splines where the driveshaft slides in, too. You might need a shaft if it was run without moly for a long time.

You should have a read through: How to replace your universal joint (and driveshaft)

[grimreaper615]

Would that be the shaft through the trans? I'm an auto tech so I'm great with cars. Not bikes yet tho lol. And I've heard there's a tool needed for the rear swing arm also

[grimreaper615]

Also thank you for that read through. I'll probably end up doing it myself with it being so detailed. Already bought the manual book. Just waiting for it to arrive. Yall on the group are amazing. Thank you all so much.

Partzilla is so good
