I went with the Lemforder and they looked just like the originals and had no problems. As was pointed out, I think Lemforder is OEM and the safe bet.

I used PSB for the thrust arms bushings when I had the dreaded front wheel shimmy when braking at high speed (over 70 mph). Would never go back to rubber bushing on a X.

That’s pretty much we’re I am as well [emoji106]. When I have to do body bushings I’m planning to use the PSBs as well. Thankfully I’m not there yet [emoji16]

Poly bushings tend to bind and cause issues. If performance is desired, spherical rod ends are the way to go. But of course they have their draw backs.

Or, delrin bushed greased bushings.

Otherwise, rubber is best, as long as the deflection is modest.

I just did this job and I went with the Meyle. The stock bushings are not solid, the Meyle ones are.

I will likely use the PSB bushings in mine when the time comes and take the extra step of drilling and tapping each housing to add a grease fitting [emoji106]

Definitely an easy enough process and goes a loooong way in maintaining the quietness and integrity of poly bushings.


I drilled the rear arms on my Notchback when I installed those arms and never looked back - love them.

I've got poly bushings almost everywhere on my X, except the subframe bushings. I went with rubber there. I have no noise issues with the polys. They do need to be greased with silicone grease when they're installed though.

I like people's comments that they don't like poly bushing but never used them. I had poly bushing on the thrust arm of the X when I owned it and didn't have the squeal or any other noise problem. People who had squeak problems probably just slapped them in and didn't bother to grease them up.

^+1 Def need to be lube with the RIGHT product before installation.
Answers on poly bushings
- Will they give off NVH on E53? Some direct feel will be noticable.
- Will you notice? 85% will not.
- Will you get better road feel and reduced suspension compression loosiness? YES (If you are running TALL sidewall tires will you notice? SOME
- Is it the right decision for everyone? Your car, your money, your time.
- Do the big V8 monsters chew through front and rear suspension parts (and tires) like candy on the day after Halloween? You bet....

Ha ha ha - I agree on both counts and really enjoyed that - “like candy on the day after Halloween” - too funny!! [emoji16]
