Hi all,

Once again the WIAIT disease has got the better of me, and I'm doing the tie rods and bushings when all I really needed to do was replace my PS high pressure line

My question is, how many washers should the new poly-urethane upper a-arm bushes be fitted with? Mine came with 2 washers total in the box, so presumably one washer per arm, where the inner large-holed original washer went?

My confusion arises because the motorsports instructions make it sound like there should be an inner washer on both ends, i.e. 2 per a-arm?

See attached pics of:

1. what I think the assembly order is based on the parts in the box
2. Part of 928motorsports instructions - looks like 2 washers on the spindle inside the arm ends? Does this mean I'm 2 washers short?

I'm off to bed as its late here in Australia.. but hopefully someone will give me a definitive answer - the only thread I found searching earlier was this one about a failure, so I'd like to get this right

Thanks for the assistance

 

When I got mine from 928 MS, there was an additional set of washers in a separate bag that said, 'Use these instead', and it was stapled to the instructions. Presumably that was specific to my MY application and I'm pretty sure you're right (I haven't done that job yet). If I were you, I'd just check with 928 MS.

 

When I got mine they came with incorrect washers. (I.D. too small) I called and they sent
me out a new set of washers. Be carefull of the alignment of the center hole too, the
first set I got were not aligned in the center.

I'd have to recommend not doing this 'upgrade' unless absoutely necessary. I cosidered it a nice
WIAIT when I was doing my shocks. For one it was a major PITA to get the A-Arms completely
removed and two it really made the ride 'harsh'. I feel every bump in the road a lot more than I'd
like to.
It turned out that the orginal bushings were in fine shape once I got them out too.

 

So how many is the right number of washers? 2 per side (4 total) or 1 per side?

Unfortunately, I don't have a choice for putting in the polyurethane bushes - a previous owner fitted solid plastic bushes and the ride has already been unbelievably harsh. My PPI mechanic recommended I replace them immediately, and that was a year ago

The nasty solid ones were so solid, they couldn't be pressed into place - they were actually in two halves with the join hidden in the middle.

Hilton, I got 4 washers in total, 2 each side and a PITA it was!

 

You need to measure it out with the larger type of steel washers for the inner and outer part of the urethane bushings.

On the installation, you need a press. There is little way around this. You will also need some urethane-friendly grease like "super lube" which is a flouro-based grease. The angled shoulder needs to be cut down to have them fit in, and putting them in in order is important - not that I can remember the order.

 

And andrew bent his - so be careful.

 

Thanks Robert - I'll grab some more of the same size washers on my way home today.

I have a press, and agree that one is definitely needed to do this job.

To avoid the problem Andrew had, I'm using a handy mounting plate off an engine stand; its exactly the right diameter of tube to support the frame of the arm and press out/in bushings, and the right height to do it with the other end of the arm unsupported, so its not possible to bend the arm.

I'll post a pic of the setup when I get home tonight.

Thanks guys!

 

Do these bushings squeak at all? I have access to mine now and was looking at replacing them.

You need to use the proper urethane-friendly grease - super lube - its a flouro-something.
