I had the RG on the alignment rack again Sunday and I think I finally got it right.....the back end was really out - as in toed out - on the right, and toed in on the left.

Plus the front end somehow only had 1.5* of caster on the left.

So, got all the numbers where they belong and now the car drives SO much better.

It's really nice having access to a modern alignment machine - now if I would only learn to use it right!  ::)

I think the problem with the handling is the rear bushings in the trailing arms, so I ordered a set and borrowed Dan's reamer to size them properly when they get here.

I also took a look at my rear lights as others said they were dim - and no wonder - they were coated with crud. The gaskets were so dried out and shrunk they weren't sealing anything. Anyone have a spare pair, MiniSpares is out right now......

I also changed back to my old locking gas cap - I wondered why I was going thru the first half of the tank so quickly - I completely forgot I don't need a vented gas cap as the tank itself is vented..... :-[

It's funny that your steering geometry seems to have changed, mine seems to be doing the same.  There's been a slight vibration at about 60 mph and it continues through to 85/90mph, and the steering wheel is no longer perfectly 'straight', but cocked a tad (about 1 o'clock) to the right of centered.  I might increase the LH caster angle slightly and see if it straightens out.

As I'm still on the 145/70/12 winter tires, I'll have the summer rubber re-balanced before I do the seasonal switch.

On our recent drive in Texas I mentioned that the handling was a little weird - nothing scary but it seemed like it tried to oversteer into higher speed turns, then catch itself and hold on.

Today I pulled the right rear trailing arm and found some of the roller bearings missing - I think I found the source of the nervous back end!

So I bought some repair kits and borrowed Dan's reamer setup on the way back from Texas and have started the fix up, in two weeks I have a run I want to do - a local group is doing an "A Sereis Run", inviting anything that was originally powered by an A series engine......we have the usual Sprites/Midgets, a Morris Minor or two, two Lotus 7's (well, one is a Caterham) and several Minis coming that I know about - should be fun. We're starting at Victoria British parts and running the back roads to Atchison, Ks (Home of Amelia Earhart) one of our club members is from there and has volunteered to lead us on a tour of historic sites in the city....should be a fun time and I want to be sure I'm ready for it.

I also found a leaking wheel cylinder on the left rear so it will get all new shoes, wheel cylinders, drums, hoses and so on. It's always sumthin with these cars, isn't it?   ::)

Well, it was much worse than I expected.....the rollers had worn thru the side of the cage and into the trailing arm itself. The new cage still fits tightly so I'm not sure what I'm going to do about it yet. options include putting the new cage in and calling it good, or taking it up to school and boring the hole out round again and making a sleeve.

The bronze bushing was still in good shape...

I took the parts up to school today and bead blasted everything clean, so it is all ready for paint.

 A few pics to show what I'm dealing with.....

If that was not repairable I was going to suggest getting a refurbished trailing arm because I seem to remember Edd China of Wheeler Dealers putting one on a Mini and mentioning the cost was like 20.   But either I didn't remember that correctly, or prices have gone up a lot!   I just checked and MiniSpares offers a reconditioned trailing arm for 54 with a core fee of 55, so that's about $140 plus shipping.   Not exactly cheap.    And then you'd have to decide whether to return the old one for your 55.

How the heck do they and MiniMania stay in business?  Just selling to people who have no knowledge of the Internet?

Makes sense.  Good luck!

I think the majority of their customers aren't aware of the fact they can buy stuff straight from the same places MiniMania and 7Ent get their stuff?

But then I have Mini owners at our local Mini events come up and say "there's a Mini forum"?

I mean.....really? The day after I bought my '03 JCW I went to Google and found the forum, that weekend I went to my first local club event where I met Don Ipock, who also had just bought his JCW.

So, I got the first one done tonight, Dan's reamer worked a treat once I figured out how to use it. Overnight I'll let all the paint dry on the backing plates and other little parts, then put everything back together tomorrow night after school.

For those who are going to give me grief for painting the control arms silver - it's what I had on hand. I like how it looks actually......the brake backing plates are black and the drums will be silver too.

It's a lot of work, but the bead blaster really does a nice job on cast iron parts like this, but these are a bitch to prep......when you go to wash all the grit off you find that it's a hollow casting and the solvent tends to pool up inside and it's hard to get it all out.....I used a lot of air, blowing solvent out of the insides of this thing.

I'm surprised just how rusted the inner shaft was, almost like it sat in salt water for a while. Either that or water gets trapped inside and cant get out again - but the emergency brake quadrant pin was rusted just like that shaft on the inside.

Weird too that the bushing didn't look worn at all, but the shaft was a rusted pitted mess.....pic is after I cleaned it up on the wire brush. Stainless steel shafts would make a lot of sense here......

wow that was really worn out I think I'd just press the new bearing in with a little epoxy in the low/worn spot of the arm to help support the outer race and call it good. The metal look of the paint is good no grief here. I wonder if stainless could be made strong enough?  Although now that you own it and it will get proper greasing it shouldn't be a problem again.

My old mini uses a bushing in both ends of the arm I wonder why they went to a bearing on one side?

Good question....it's interesting to me that the bushing is on the outside and the needle bearing on the inside too, seems like the outer one would have more stress on it. Plus too and also, just like in the front suspension the shafts that ride on those needle bearings don't turn very far - only a few degrees -  so all the pressure and wear is only on one side of the bearing.

I thought about adding some JB weld on the side that had the wear, but decided just to press it in and call it good - the bearing fit tightly so I think it's supported well enough.

And you're right, it will be lubed properly and won't be driven under water!   ;D

I am thinking that the bearing is on the inside because that is the side that the suspension pressure is on mostly.

I agree, it just seems to me like the outer would carry more load, dunno why....most wheel bearing setups have the larger bearing on the inside too.

today I got the backing plates reloaded with new wheel cylinders and shoes - however I'm disappointed in my circlip tool, didn't work worth crap! All that happened is that as the circlip got spread down the cone it dug into the cone and locked up, and dug a hell of a divot in the cone too. I went back to my old method of installing the circlip and it worked perfectly.

I bolted the backing plate and emergency brake cable bracket on and installed the new brake hose, so this side is ready to go back on the car now.

I had pre-greased the bearing and bushing, but after I got it all together I pumped a bunch of grease into the shaft till it came out the other end, then rotated the shaft to try and make sure the whole thing was coated in a layer of grease - maybe that will keep it from rusting like the other one did. I also put a good coat of grease on the quadrant pivot pin, the part that was inside the training arm looked like the shaft, all rusty and pitted, but the parts that go thru the arm were clean and fine.

I guess I'm not alone by pumping grease till it oozes out the other side. Ashame about the circlip tool.  Guess I'll continue the fight without any tool.

Speaking of grease and of the circlip tool, do you think a light coating of grease might have helped?

I see Michael has posted Seven's instructions to use the circlip install tool on the MiniSpares thread.  They recommend grease.
