If you look in the Bentley Manual at pics of the factory rubber bushings and how to install them, it appears that VW designed the bushings for more sideways deflection than vertical in order to dampen some of the roughness introduced into the steering by such things as potholes.

Remember, the Vanagon really wasn't designed for high speed paved roads or severe off roading - it was designed as a work truck or a vehicle to bring down the hay from those high Swiss pastures that the cows didn't eat! Things like that.

Maybe so, but I no longer bring hay down for the cows.

That is what shocks are for. You can orient the OE rubber type either way and it won't help the steering.
The ride hasn't changed for the good or bad other than the driver input into the steering is now much more predictable.

My brother is coming over from the UK( no shipping , taxes etc), so i am getting this powerflex kit sent to him from brickwerks;

Lower arm inner bushes (Lower TCA bushes)
Anti roll bar drop link to lower arm bush kit.
Anti roll bar drop link upper bushes.
Antiroll bar to body bushes
Steering rack bushes

Are there any other bushes i should be replacing at the same time, or is this enough ???

thxs Mick

My understanding is that the guy at Brickwerks does not like how the Powerflex upper control arm bushings fit in the Vanagon but they are available. The other bushings to replace in a front end work are the front lower radius rod bushings but Powerflex does not have those available for Vanagons.

Just wanted to chime in on the Powerflex steering rack bushings. First off, Loogy is a great guy to buy from and they got to me fast.

I will second everyone else's comments about the improvement with these. You know that dead feeling around neutral when you're fighting a crosswind and jerking the wheel back and forth just trying to stay in your lane? Kinda feels like your old Bug with a worn out steering gearbox? That is gone. Okay, she's still getting pushed around by the wind, but lane positioning has become much less of a guessing game.

As for any harshness, forget it. Absolutely zero new vibes in the steering wheel. I remember when I put urethane transmission mount bushings in my Bug and hated them. This is not the same stuff - it's much softer.

Just fitted my powerflex steering rack bushes this afternoon and i think i may have a problem ???

i followed the instructions as per this thread- took out all four bolts, replaced bushes and re fitted with correct 18lb torque. I turned steering wheel to assist with this, gaining space to fit new bushes and to re-align and bolt steering rack back in place ( id did this all with the front wheels on the ground- if this makes any differance ???).

On driving van it is has very tight steering on the straight ahead, no self centering etc the steering is super stiff and "dead", i can turn the steering 1/4 turn and it just stays there, like its "too tight" !!!

Have i missed something, done something wrong ???

check your steering coupler and the rubber bushing.
http://www.van-cafe.com/home/van/page_210_763/steering_coupler_1980__1991.html

Its possible that when you moved the steering rack to fit the rack bushings, perhaps something bent?

Or the steering bushing, itself has failed?

Pics?


When I did this job I detached the linkage at the coupler bushing.. and that created adequate room to move the rack forward with out any prying.

Still kinda stuck with my 'TIGHT' steering after changing my steering rack bushes, my mechanic ( over the phone) thinks i may have let the steering column fall while the rack was loose ???, he suggests looseing off the steering " knuckle" and pushing rack back up and then re tighten......not exactly sure waht he means and where this is located/how to do it....any ideas/help ?

Look in my gallery of photos, fourth one down, your steering column may have dropped out of the 2 pins that hold it together.

Are you sure that the steering shaft from the steering rack going towards the front bumper isn't dragging on the spare tire. You are going to have to poke around and look at what doesn't look correct as something got overlooked, this is too simple of a procedure. This is a odd one.
Good luck.

Are the radius arm bushings available yet? I saw them on the Powerflex site, but Loogy's site doesn't list them. Question

They were supposed to arrive in the latest shipment, but they weren't included. A quick note to Powerflex revealed they have not left Europe yet. I have note in to them, asking when they will be arriving, but I haven't heard back on that yet. They should be here soon though.

Can't believe you'd put such a nice piece of art out on your driveway like that!!

I find that stark juxtapositions like that evoke strong emotive responses in my audiences.

I'm mesmerized by your jaunty arrangement of the protective covers. They draw the eyes upward, then allowing them to playfully sweep in a poetic arc down and then back up across the sensual curves of the rack. bravo, sir...bravo
