Let me state right away. I did not buy my bushes from Carl, so this is NOT NOT NOT a complaint about his product. I bought them yonks ago. I just downloaded his instructions 'cos I figured Urethane bushings are Urethane bushings.

So just how are these things supposed to go in. Carl's instructions say "grease the bush and pound it into place with a hammer". Yeah right I reckon Carl must have a much bigger hammer than I've got - If I'ld done it that way I'ld still be watching the bush slide in a bit then bounce right back out over and over and over.

The first bushing goes in easy with a vice and a socket to support the back of the A arm.

I tried everywhich way to get the second bushing in (the difficult one because you have to have the Pivot bar in place) and for some reason this time (this is the third A arm I've done in the last couple of weeks) I just could not get the second bushing to seat properly. (And I tried everything - think of a combination of shop press, pieces of angle, tube, long lengths of threaded rod, hammers, crowbars, bits of timber)

So who has cracked this proverbial nut and found a simple way to get it done simply and easily.

For now I got far enough in that I can get the nut on with the big washers on the end so it's reinstalled - will keep an eye on it to see if it settles itself with some driving - if not it's all coming back off.

Last time I did poly bushings I had to trim them slightly. I added a couple of grooves and put some grease in them which helped a lot, but definitely a big hammer and a vice are required. However I'd never do it again. The grease was gone in less than a year and the bushings would seize the suspension, releasing with a sudden bang - this was on a very light car so a 928 might not have that particular problem. They squeaked horribly and it was just not worth it unless you're doing a track car and want that extra precision, and in that case I'd save a bit more and put in heim joints and bearings.

What are you lubricating them with? There are lubricants that are specially made for poly & poly bushings. If you are not using one then do an internet search for them.
I believe they are usually paraffin based

My dad used to throw poly bushings in the freezer for a few hours prior to hammering them in. It was still tough, but they would go in.

You need to grease it with this grease (Superlube) by Synco, and it is made with teflon:

Because it does not react with urethane, and it does not get washed away by rain or... whatever.

The angled end needs to be trimmed. And they need to be pressed in with a press just like any other bushing.

I had a professional with a good press do the second bushing, hammer did not work for me!

Are you sure you have correct version? There are two different sizes, '78-85/86.0 and '86/86.5-95. Older is larger and do not fit into newer arm.

Lubed with Teflon based grease. bushings correct for MY. Just the impossibility it seems of getting the second one with the pivot bar in the way.

The difficulty is supporting the A arm in a way that directly supports the end of the A Arm into which you are trying to press the 2nd bushing. The ties on the lower beam of my 20 ton press prevents supporting the edges of the arm using a pair of angles. So using the press is at the moment not an option.

The problem is arranging the bush and arm in such a way as to apply pressure. THe amount of pressure required is low - ie using your finger to pump the shop press is enough - no need to use the 2ft long handle.

Only one left to do - (and one possibly to redo if the bush doesn't seat itself in use) - I'll think of something eventually.

mark, ive had poly bushes everywhere in my 928 and they are behaving themselves. the upper A arm bushes are a good mod as they increase the precision handling of the front end.

jon, i took mine to chris at loe bank. i recall he wanted the phone number of the supplier when it came time to install the lower A arm bushes, to ask how tight they were ment to be!

Need to use a press. Hammer anit gonna work.
