Hi all,

Whilst removing the steering wheel off my 1996 300tdi, I accidently hammered the 1/2" square hole of a socket onto the steering column's thread. The thread is now screwed.

182425388_10165245433745711_8020032003132668968_n.jpg


So, I'm looking for a tool to rethread it but can't find the specs of the thread anywhere. Every parts list I look at says that it's a 14mm nut, but mine has a 22mm nut. Any suggestions?
 
Probably be cheaper and safer to fit a SH column, I can't see anyone wanting much for one?
Try an ad in wanted..?
 
Oh, and 14mm probably means M14 thread, the spanner size is irrelevant.
My nut is 22mm spanner size.
 
Well you've really f**ked that...!

The easiest way to clean the thread without removing the column:
  1. clean up the column shaft and thread with wd40 and some 1200grade - get rid of that crud before you start repairing.
  2. once thoroughly clean, take a junior hacksaw blade and "very carefully" feather cut the damage threads by pulling the hacksaw blade [do not try to force forward cut...] following the thread/s.
  3. repeat pt.2 until the thread burrs are removed, then re-die/cut the thread making sure 1. thread is properly greased, and 2. do not force re-thread, go very gently - 1/4 forward, 1/8 back and keep feeling for tight points. You can always ease off, clean out any swarf, re-grease and continue thread cut.
eta:

1. 22mm metric nut is a 14mm thread
2. do not be tempted to use a st/st nut on this - you'll gall whilst torquing up

14 mm die nut should clean that up, be sure you get the right pitch.
Put some grease on and then work the die down slowly half a turn then back until you get it to the end. Looking at the picture worst bit will be starting it take your time.
 
Only "partially buggred" not "Fully buggred". Should clean up with a file a hacksaw and some patience.
If you can get the worst damage off a re-thread with the appropriate die and some cutting oil/grease will work wonders.

How the hell do you ‘accidentally’ hammer a socket onto it :eek:

Mullered nut and a shallow socket combined with a lump hammer I guess.
@Glyn D are the bushes/bearings still good in the shaft? Lot of rust there and the (cough) accidental hammering might have damaged them?.
If you can't save it you could drill and washer/split pin it but I would be looking for another SH column long term.

Thanks guys. Hadn't thought to use a hacksaw on it.

Remember, you're feather filing the thread using hacksaw blade by pulling the reverse blade through the thread, not forward cutting. And go gently...it's far better to take twice as long and complete the task properly rather than attack the job and **** it up [again...] ;)
