Upper strut mount nut removal

[Url]

Does anyone have any good tips on how to remove the front upper strut mount nut?
Any tips on how to keep the mount with rubber underneath from turning along? + Is it normal that the lockplate is "bended" upwards to the nut? I already bended it down, sprayed WD40 multiple times but the nut still won't budge ...


Thanks!

i use an air impact.

I don't have one (yet) Any other suggestions?
Other question: can you "break" something if you twist the strunt mount too much? (rubber etc.)

sorry for my feeble memory. but doesnt that large washer have a pin that slips into the slot on the shock's threaded shaft? can you grab it with large channel locks? and counter turn it?

+1. There is a thread with picture on this. I used this method, works.

try a cheapo manual impact device

WD40 is NOT a penetrating oil BTW - buy loctite freezeoff, kroil or pb blaster etc. - time and tapping are needed (hundreds of taps over several days)

never seen a lock pin but you can use big pliers on these things

I ended up with my Dremel - second best if you have no air impact at your hands. Anyway you can not re-use the nut.

I fought this thing for two days about a month ago, many four-letter words were involved.

In the end it was a pipe wrench on the washer that did it, but even that took a while because it kept slipping off the washer.

An impact solves all of your troubles-no worry about twist, breaks the nut loose, etc.. Buy a heavy electric version if you don't have a compressor. Every tool box should have an impact, especially working on older cars.

+1 for penetrating oil (kroil or PB Blaster) and an impact gun. Air or heavy duty electric. If you're going to do work on a Porsche it is a massive time saver. What will take you hours with hand tools will take minutes with a gun.

Use a decent pentrating oil.

Grab the big dished washer which a pair of channel locks or pipe wrench, the washer has a key that fits in the slot of the spindle nut.

Hold channel locks tight (a helper is not a bad idea) and use a box end wrench to turn the nut.

Won't budge? No impact wrench? Make your own! Wack the box end wrench with a hammer while assistant holds washer with channnel locks.

Lather, rinse, repeat.

Why not?

Yep,

It is the third item from the left on the lower row of this picture:



Thanks Fleming

I'm sure an impact gun is the "best" answer, and hopefully I'll have one someday. But in the meantime, the pipe wrench I used was $14.

Hello Harry,

get a new one! They are self securing, if you take a close look you will see, that they are not perfect round shape. It is more "oval" so the nut fixes better when put back. You will have the same trouble fixing it again without impact wrench.

I cut two flats on the washer so I can hold it with a wrench, instead of fighting with channel locks and such.

[herr_oberst]

The pipe wrench did the trick for me, and IIRC, the new shocks came with new hardware, but I like the idea of two flats on the washer...

I second the use of a pipe wrench. I just did this job this past weekend. An 18 inch (made in USA) pipewrench to hold the round disc and a breaker bar on the nut did the trick easy-peezy. I replaced my Boge inserts with Bilsteins.
