Lower trailing arm question

[whowey]

The Expy I am looking at has a rust hole the size of pen tip in the lower trailing arm.

So I am going to get a replacement set of arms. Who makes a good set of replacement arms, that use either round tube or square/rectangular tube rather than a factory mess???


I found some on Evil Bay from Expy Source.. but I really can't find much info about them anywhere else.

I replaced both of my upper and lower control arms with pieces from PMT.

PMT Fabrication. 97-02 FORD EXPEDITION/ NAVIGATOR REAR TRAILING ARMS

I second PMT, I also just put in a set of lowers. I waited till the rust hole was the size of a quarter... I go to college so money was tight haha. I feel much better going into the MN winter knowing I have the PMT's than the factory ones I had last winter.

Thrid on the PMT I put upper and lower , nice quality

Can always look at some Rancho bars and put those on. They are much beefier than the stock stuff. Even more so than the PMT. The big trick with them will be finding a set. But, you may get lucky and find someone selling the back half lift kit for an Expy. never know what you can find.

i've been rocking the expy source ones for a year now, very beefy square stock. Mine looked like swiss cheese before replacing, good thing your doing yours now, I had to re-center my rear end from the factory mess being so weak. Got rid of a mild driveline vibration too..

You wouldn't know off hand the size of the bolts?? I have dozens of grade 8's off all sizes laying around...Not having to buy new bolts would be great.

yea, in the how to link i posted i put the sizes in there, and i am fortunate enough to have a shop that sells grade 8 bolts for cheap and even higher alloy bolts that they use on rollercoasters. Make sure you use a locking washer with the bolt too.

5/8 x 18 threads x 3.5 inch bolt (i only needed 1 as i reused 3 of the old bolts)

Thanks... I looked at the link. I didn't see the bolt size, but I didn't really read it thoroughly.

My shop at work has 5 gallon pail after 5 gallon pail of bolts sitting in it. We are involved in high liability construction, so we swap bolts out every job.
