Removing the Nearside Front Suspension

The chassis legs need sorting and to see what's what and make the repairs (whatever they may be) the front suspension needs to come off. This week, I have been mostly tackling the nearside...

The Haynes book said remove the tie bar first, but the bolt just wouldnt shift, so I'm going to come back to it later. Great start.

I carefully removed the brake drum then wiped it down inside with a damp rag. The brake dust inside the drum will likely be asbestos so dont want to take any chances there. I just chucked the brake shoes. They're old and I will be putting some new ones on anyway when I reassemble.

Removing the hub was a little tricky as I didn't have a hub-puller, and any leverage easily slips and just spins the hub. A post on the http://www.morrisminorowners.co.uk/ forum and I was back the next day to try a couple of things. It turns out that using a wooden lever was less prone to slipping than a metal one and the hub came off easily...




With the hub off, I thought I'd start on the suspension itself. I removed the nut holding the top trunnion onto the damper arm, then decided to try and remove the steering arm. I got as far as removing the nut, and no matter how hard I hit it, the steering arm did not want to shift. On reflection, I dont know why I was trying to take it out anyway. There's nothing that needs to be done to it, and it's not like it suffers from wear etc, so I'm happy to leave as it is!


Defeated by the steering arm, I thought I'd try removing the track rod end. This was done by removing the bolt on its underside that held it to the steering arm, then since I don't have a ball joint splitter, I shocked it out of the steering arm by giving it a good hearty wack with a hammer.


With everything pretty much off that needs to be, I removed the fixings that held the front half of the lower suspension arm in place, and took it off. Note that bloody tie bar still floating about.
 

I felt a bit of play in the bottom trunnion earlier on, and it looks like this is the source. Excessive wear on the bottom fulcrum pin. According to the guys on morrisminorowners.co.uk this is probably caused by the fulcrum pin becoming stuck inside the trunnion, and not rotating as it should. Notice the "notch" on both ends of the fulcrum pin...
 
 It turns out, that this fulcrum pin not moving freely as it should, has also caused this elongated hole in the suspension arm. Suppose I'll be needing a new one of these - and I hope the torsion bars aren't buggered as a result.

I recon I've got the same to look forward to on the other side of the car. The problem has been caused by poor maintenance, so it's unlikely that one side has been maintained well, and the other not. Still, I've learned what can happen if things aren't greased/maintained properly.




Book - "Guide to Purchase & DIY Restoration of the Morris Minor & 1000" by Lindsay Porter

I bought this on Ebay a few months ago and have used it quite a bit for the stuff so far. It contains a brief introduction to the car and its history, and a useful guide to buying (faults to look for, checks to do etc etc) as well as the normal maintenace stuff.

Its probably only any real good for someone without much experience (like me) because the stuff inside seems pretty straight forward and I doubt that anyone with a good idea of what to do would need this really. I've found some useful tips etc in there, but I have a pretty limited knowledge of this sort of thing, and for the most part even I think that what the book is saying is common sense. It's still useful to me though - to make sure I'm doing things right.

There is a useful reference section at the back of the book which includes colour schemes, explaination of chassis numbers, and production changes.

This is now out of print I think, but its still available on Amazon.com last time I checked.

Pro's: The step by step stuff is useful to follow for beginners like me.
Con's: The layout of the pictures/steps in the book aren't the easiest to keep track of.

Cleaning the gearbox

As I'm removing stuff, I'm trying to clean it up. Hopefully this will make it a bit of a cleaner and easier job when it comes to putting things back together. The gearbox was pretty minging dirty and it took a bit of shifting with a wire-brush so thought I'd try using some Gunk Engine Degreaser. I mixed it 1:1 with paraffin just to make it last a little longer, then used a jet-washer to rinse it all off. The paraffin left a oily residue so used a light brush of neat gunk to clean this and then jet-washed it off. I'm pretty pleased with the result.
