1990 FJ62 (1 Viewer)

I have 2 issues I need help resolving - severe bump steer and no power (crappy MPG). I have stock 6 cyl with automatic trans w/overdrive. I bought it with an old man emu lift 4” or 6” not sure which on 35” tires. I “think” a dropped steering arm will help bump steer but need professional help as I drive my family around occasionally and want it safe. Then what gearing is recommended for my 35’s? Trans was rebuilt only 10k ago so not interested in changing that. Thanks in advance!

For steering I'd say, check the tie rod end and drag links. Also might want to check the steering dampener.
No power...well, its a FJ62, they were under powered from the factory and A440F tranny didn't help. If I'm correct in thinking, 35's should make you slower to start but get you better MPG at highway speeds. Factory gearing on the axles should be 4.10 if that helps.

These are the recommendations from Cruiser Outfitters

62 with stock 4.11 gearing:Going to a 33" tire size: 4.56, 35" tires, 4.88, 37"+ tires, 5.29 ratio ring & pinion.

Hi, Personally I don’t run anything bigger than 33s on our rigs,they are daily drivers. Anything bigger is TOO Slow without regearing.check tie rods for sure and alignment. Slow ,yes, look at what it weighs. Mike

Thanks for the reply steering is tight and has a new dampener.

Awesome thanks for the information!

Thanks for the reply. Steering tight and is aligned. Not looking for speed the thing is a tank. Just looking for feedback on gearing. 1/2 drive I burn over a 1/4 tank of petrol.

Were the correct shims installed on the front axle with the lift springs?

Step down to 33" tires. You and the 35 year old vehicle will be alot happier. Stock gears will be fine with 33s.

All this power and MPG talk is subjective to you. How slow is slow? "1/2 drive I burn over 1/4 tank of petrol" means nothing to us.

Lets see some pics of the whole setup.

Agreed on above, what caster shims are in it? My old 62 I ran 4.88’s with 33’s and in my opinion it was perfect. I’d want at least that for 35’s if not 5.29’s.

How was the '62 on 33's from a stop and going up hills. I'm thinking about getting 33's, but I live in the mountains and it already struggles at times

It was peppier than my current 60 on 31’s and stock gearing.
