Front Suspension Rebuild - Best Parts / Sources


Recommended Posts

Hello,

I have a '73 2002 Roundie and the rubber crumbled in the swing arms so It has been laid up for a year and a half.  Shortly after the layup, I picked up a front subframe as the current had minor damage.  I want to by all new parts except shocks (good) brake assembly and steering box and put it together, drop the old sub frame, and slide the rebuit in.  I've been through the process with a '74 in the 90's so that aspect is cool.  Just need some help on sources and any minor performance upgrades available then the OEM.  Stock arms seem the best, but ball joints, control arms, sway bar bushings and all the bolts - oh my -  can leave my head spinnig as whats good quality wise and of course the price.  I'm leaning a little on the mild performance side so if anyone has source/ selections, it would be great to hear some feed back.  I've been receiving emails from Walloth u.Nesch for a while but never bought anything and unsure of the quality.

Thanks in advance for any info...

I know you said you only want to do a front overhaul, but why not everything else while your at it?

Are you looking to use rubber bushings or polyurethane?

Hi TK, +1 on Blunt and +1 on doing everything. I did my whole car and went through Blunt except for a couple odd bolts I got from Atlanta BMW (http://parts.bmwofsouthatlanta.com/productSearch.aspx?ukey_make=980). He was a great resource of info and got me all the parts together in one shot. For me the front was the hard part, so if you're gonna do that I'd highly recommend doing the rear also.

 

I went with rubber based on Steve's (Blunt) recommendation (street driving for fun, no tracking) and LOVE my 'new' car.

 

As far as 'upgrades', I think IE makes a better arm (bent "I" shape?) but someone on here can speak to that better, and of course there's the boxed ones. My understanding is that our stock arms are a weak link in our systems.

Yes, there WAS skin on my knuckles before I started the repair...

I used Poly bushings from IE and the rest (Ball Joins, tierods, etc) was from Blunt. Only way to go!

I just found this source for fasteners, washers, etc on the front suspension rebuild.  Worth it to have new parts for me, anyway.  https://www.wallothnesch.com/en/front-axle/bmw-1502-2002-turbo/catalog-picture-31-01.html

It's been 9 years since I commented in here...that's unrelated. 

 

 

But if you have the means, I recommend getting your car's nuts and bolts re-plated in yellow zinc. Everything will fit better than the aftermarket kits from my experience.  It will take you more time between shipping and replating, but I have no regrets and prefer to go this method. 

But if you insist, Ireland Engineering offers these kits as well. They may be working with Walloth Nesch as a retailer here in the states.

Beauties!  I hope mine look that good!

 

Pay close attention to the location of the hardware.

 

In the photo above (referencing Jim's photo with green background), it appears the washers for the tension struts are not correct. The larger washer (p/n 31122614158) is #9 in diagram (in the photo, the larger washer appears to be at location #12). -KB

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
