Bag E contains all the parts to complete the front end of the buggy including the drivetrain, the steering and the suspension.
There are a lot of new parts in this bag. First, Team Associated has included the Factory Team blue anodized steering blocks, new lightweight aluminum stub axles, redesigned caster blocks, new a-arms, new sway bar drop links, new upper arms, new inner hinge pins and new sway bars. That makes a lot of new parts!
One of the very first steps is to assemble the steering blocks into the caster blocks. This step is very important and requires attention. This is explained in the instructions manual but I will repeat. The short bushing and the short screw are used for the top and the long bushing and screw for the bottom. Each bushing has a triangle shape at one of its end. It must face the steering block. The triangle must be keyed correctly into the steering block. I use a flat screw to key the insert into the steering block. Once it is keyed correctly, I use the appropriate screw, don’t use the screw with a hex on both ends, they are the droop screws. Don’t forget to apply thread lock to prevent the screws from coming loose. Once assembled, the steering blocks must move freely within the caster blocks.
We must apply thread lock at many places for this bag, A good trick is to pour few drops on a plastic bag on which I simply dip the screws in to apply thread lock. This makes application of the thread lock much easier.
For the next step, make sure you install the new sway bar links in the right direction, the pivot ball must point backward the car. Install the droop screw, the screw head goes under the a-arm. As mentioned above, the droop screws have a hex on each ends, don’t mix them with the caster blocks screws.
When assembling the caster block to the a-arm. Pay a very close attention to the red and blue caster bushings. It is very important to install them correctly. The blue ones go with the writings down and must be inserted in the front of the caster block. The red one goes with the writing pointing up and goes in the rear side of the caster block. The a-arms, the upper arms and caster blocks are labeled Left/Right.
This is not shown in the instructions but you must install the hinge pin to attach the caster block to the a-arm and you also must install the retaining screw.
A small modification has been made to the installation of the upper arm. In the previous kits, the turnbuckle’s end was sandwiched between two cone washers. Now, the two same cone washers go between the turnbuckle’s end and the rear of the caster block.
Two hinge pin bushings (2 dots) were missing, after a quick investigation, I’ve found them in the bag F.
The rest of the assembling is quite easy. Just make sure you install the hinge pin bushing in the right direction (dots up or down). It is not indicated but for safety, I’ve applied thread lock to the two 3x6mm bhcs screws used to retain the shock tower hinge pin bushings.
At no place the instructions say to apply grease to the ring gear before installing the front end to the chassis. However, I suggest you to apply black grease to the ring gear and spin the pinion until the ring gear is fully greased. The same is also true for the rear diff.
