Maybe you should get a nice boring reliable gas-powered car; the
Hondas are good. You\'d have more time to design electronics.
Designing good suspension is just as fun as electronics.

We are going to add two aluminum u-channels to the control arm. The arm was bended and broken around 1\" beyond the hole toward the ball join. We need the protective channel to reach the ball join as close as possible.

Just need to bend and form the channels to match the control arm. Perhaps doubling the strength without adding too much weight.
Why did the control arm get bent? I don\'t know what an \"anti-vehicle paper\" device is.

There was an anti-vehicle landmine (2\' to 3\' cardboard box) on Van Ness at night. I avoided it by sharp turn to the right, but forward momentum pushed the left wheel sideway and bending it. It was still driveable for a while, waiting for replacement. It was stopped waiting on the sidewalk for street cleaning trucks to pass. The drop over the curb broke it completely with one wheel struck on the curb and occupying 10% of the sidewalk. SFMTA tickets it for $108 an hour later. They are so concern about 10% of the sidewalk and not concern about landmine on 40% of the road. I am going to contest it.

Their lawyers would enjoy the work of course. No court filing fee on behalf of public safety. $30 for subpoena for discovery and production of records. I want to know how long the bomb was there and when did they know and clear it.

Whether there were eggs or TNT inside the box make no difference.

Have done a few UJ boots in the past, repair pack includes a sachet
of grease. Molybdenum Disulphide. MSO4, from memory. Important not to
overpack the joint, as too much will churn and overheat, or even
sieze up.

The last joint to fail was at traffic lights,shortly after coming off
the motorway. All the balls were held in place in a straight line, but
stopped at lights, heard balls falling out to the road. Fortunately, a
Quattro Audi saloon, so engaged the diff lock and drove home in 2WD...

I am going to try a temporary fix in place, without pulling the axle out of the motor. Just remove the top layer of grease and replace with some. Superglue the broken boot and duct tape around it. Hopefully, it will last until it get replaced.

Someone suggested (he said it\'s suggestion from Nissan) to put some DC M-77 on the splinter on the wheel. Should I put it on the transmission side as well?

There\'s a special grease for this application.
CV joint grease seems to usually be a a lithium grease often with added
molybdenim disulphide. I am not a lubricant chemist so I don\'t understand
the signifigance of that.

If the only current CV damage is a torn boot it will be good for a
thousand miles or more with no attention, but the grease loss will be
an inconvenience.

superglue works well on neoprene, so if you can get it clean enough
that fix should last a long time.

The inner CV joint was pulled apart by the tow truck loading. I don\'t think there is any other damage on it.

Good to know. I will duct tape it just in case.

From brief internet research, CV joint grease is similar to M60 (with some moly). M77 (high moly) is for the spindle and gear.

Moly is for high temperature friction lubrication.

Some shops use cheap wheel bearing grease mixed with some M77 instead.

I can afford expensive ($20 per spindle) pure M77.

Should I also put M77 on the ball joint?

I got a 20,000 pounds BJ pusher, but I need an adapter. I think I can use two 2\" pipe caps and a nipple. Cut a hole (slightly less than 2\") on one side to hold the BJ and a 3/4\" indentation to hold the pusher. This will only work for the Leaf, since every car\'s got different BJ.
