4000 series hub / upright / spidle options

What was the cause of the sqeak in the rear and the sound of the driveshaft hitting? I think you said that was one of the initial problems.

I got it all back together and took it for a little test cruise (~5 miles) on Hwy 17 (Mt Hermon Rd to the next exit Granite Creek / Scotts Valley Dr). Everything seems okay but I will put it on the lift and check it once it has cooled off.

It still squeeks but that is most likely rubber suspension parts that just need to be lubricated. The "drive shaft" noise is gone and I don't actually think it was ever the drive shaft since there was never any evidence when I put it on a lift and looked that it was hitting anything. My mechanic found a whole bunch of loose things in the rear suspension and tightened most of them when he was giving it the once over. I still have to get him to finish looking at it. Not cheap, but a trained eye is worth its weight in gold.

Doe any one know what the torque on the big nut on the back of the up right is supposed to be. We preloaded it to what specs we could find (which put the nut about where it was on the driver's side and a little past where it was on the passenger side) but the bearing still seem to have a little play when you garb the tire top and botton and try to move it in and out relative to each other.

I will take some more (longer and longer) trips and then re-inspect everything and hopefully call it good.

Glad you got it all squared away John. I was going to suggest you have the two alloy parts welded together before putting them back on but I didn't catch you in time.

Thanks Sal,
used to be able to do a decent job sticking things together with a mig welder. Not sure if sticking the billet aluminum upright to the steel ball joint mounts would work. I also know so little about welding that do you have to worry about changing the temper when you are welding? It is back together for now but it will be a while before I trust it. Sad, but after being betrayed a couple of times, it hurts. Thanks again

Oh, didn't realize the upper mount was steel, thought both parts were alloy.

I thought they were both billet when I looked at it the first time (which scarred me because in my little brain I thought that aluminum trying to hold a threaded fastener under that kind of load would be bad).

John,

Great to hear you're out doing some short test runs. I'm taking a little sabbatical right now (), so I'm open for a mid-week drive.

After all you've been through with your car lately, lunch is on me in Davenport one day.

Email me when you're free.

Wednesday 4/1 works for me. Maybe I'll start a new thread to see if anyone else wants to come out for a mid-week drive and lunch.

An Excellent idea. I doubt many people will be able to play hookey or get a hall pass, but it is worth a shot. We can finalize times and where to meet for the drive later. Go ahead and start a thread and let me know when you do.

Ya know, my neighbor has a cobra that I have never seen him drive in the two years I have lived here, maybe I can twist his arm

I think you're right. Maybe the nice weather will lure some people out of the office for a quick run up the Coast and through the mountains.
