I've been reading about it, but haven't found anything that is exactly my issue. I have an 1987 22R 4x4 5 speed. U Joints are recently greased and just flushed and refilled T case with synthetic. It's chirped all of the way through these things and still continues to chirp. Chirps, intermittently, when rolling and can be heard best in 2nd or 3rd gear. Any faster and my magnaflow drains it out. Doesn't matter if clutch is engaged or not. I really don't think it's a bearing as I had those all checked and the front two repacked 5k ago. Any ideas?

I recently had the same problem. My issue was that the Speedometer cable was old and worn and it went from a chirp, to a whine/squeal, and now it is a full on concert when I drive down the road. Watch your speedometer and see if the needle starts to jump a little when the noise starts.

I've been putting off my speedo cable for 2 years now. Sounds like my truck is hamster powered

Mr. Magoo

Same here. I just kept turning that radio up and up until I just couldn't take it anymore. Bought one from the dealer. Quiet as a church mouse now.

Wow, thanks. The speedo does jump slightly when under 30 mph, that's gotta be it! How much of a pita is the job? Pretty new to wrenching, but have been conquering the smaller jobs Thx!

Mr. Magoo

It shouldn't be too difficult. On mine, I just removed the plastic pieces that surrounded the dash, and pulled out the dash just enough to disconnect the cable. I then disconnected the cable from the transfer case. After a little bit of fishing it through the grommets and clips, it was out. I would recommend buying one of the repair manuals from the auto parts store on your truck. It makes wrenching SOOOO much easier.

i had same issue on an old datsun pickup - try disconnecting the cable behind the gauge cluster and toss some lubricant inside the cable sleeve. I think I used graphite, but don't recall. it's worth a try for 10 min of your time.

Or you can drive with it disconnected to verify if thats causing your issue or not. Easier to disconnect it at the transfer

Slightly concerned about "tampering" with it. I have a completely stock truck with 35k original miles on it (barn find). Would hate to screw up the carfax or something...

j2the-e

Are you thinking the truck has some sort of device on it that alerts carfax if you drove once around the block with the speedo dis-connected? I can assure you it doesn't

Discombobulated

Well you better not do any burn outs or roll your tires on the jack, carfax will haunt your dreams forever I'm voting graphite in the cable. Taking it out to lube or replace will not do anything to your mileage and its not difficult, search the forums plenty of threads on speedo cables.

Oh and post some pics of this barn find please.

I had that problem years ago, unhooked it from the back of the cluster and dropped some penetrating oil in the cable housing and fixed it right up.

More about a mechanic or dealer reporting a disconnected or faulty cable if I can't finish/do the job myself (very possible that I screw up a job [new wrencher])...

Also, it's intermittent. I was driving around today and the needle had a little bounce, but no noise. The chirping came back at one point when the needle wasn't bouncing?

I've replaced it a couple times, no biggie, but go slow and set aside a couple hours the first time. I've never seen how to get lubricant into the cables...they seem pretty well sealed at each end.
The Haynes manual explains the job pretty well, the FSM(more $$$) has the same illustrations printed a little more clearly.

Here's a good thread and a neat way to grease the cables. Hope it helps someone. Good luck figuring out the chirp.

You never really said where the noise is and the thread just degraded into a speedo cable thread Are you sure it's not your brake squeelers, or the dry bushing issue on the front axles.

Best to diagnose it than just throwing time and money at things that aren't your problem.

Just unscrew the cable from the bottom and take it around the block, this is what your mechanic will do or should do to isolate the isssue. The mileage on a toyota is just a toyota pride thing anything over 100k and "normal" buyers just assume a "normal" auto is junk now a days anyway. Anything over 200k and the DMV tends to put it down as estimated mileage anyway.
