Default Great car

I have had my Pro-4 for 2 months and I am slowly putting it together to run this winter. The only thing that I have found is that the front hubs fit really tight in the C-hubs/knuckles and the lower stabalizer ball cups are tight on the A-arms. Other than that the car is great and super smooth. All I have to do is build the shocks.

Some questions:

1. I bought the Jet Knuckles, the finish looks excellent. However, the bearing housing on these new knuckles are much bigger than the stock ones. Anyone know the exact size?

2. Each knuckle is marked "L" or "R". Which side do I put each on? Right/Left looking from the back of the car or from the front of the car?

Thanx

left would be US driver side and right would be the other side...

so left when you look at the car from it's toosh...

but I dunno why it has L/R, it should be interchangable

The housing in the new knuckles are too large (about 2-3mm). I just need the exact size

Just wondering if anyone else has these Jet knuckles.

if you want the exact size to the thousandths, i don't think anyone knows except whoever did the tolerances on the stock hpi knuckles...

2~3mm is a HUGE difference... are you over exagerating it?

I've tried 2 different companies' aluminum knuckles for the pro 4 (RC square and HPI) and the bearings just slide in but it doesn't wooble and stays put

Just noticed that the tag that came with the package says:

PRO3-06
ALUM. KNUCKLE ARM
(HPI PRO 3)

D'oh!

I ordered them from Precision RC from the Pro 4 menu too.

Gotta go back and read my Pro 3 Manual

The Pro 4 Jet knuckles are an extremely tight fit as regards to the bearing sizes, but they do go in.

The problem I had last night was that I broke the ball end which screws into the steering knuckle, and guess what, it broke clean off at the steering knuckle...so how am I supposed to get that out?

Other than that it was a good night, my PRP chassis was handling great and it was really quick round the sweepers...I wonder what it'd be like with a one-way in too

Are you guys having a problem with the stock knuckles or are the aluminum knuckles just for the bling bling?
