jk4138 Posted December 11, 2006 Share Posted December 11, 2006 I have a 87 GL D/R wagon and was wondering what is the max speed that I can go with it in 4 hi? I know that vehicles with transfer cases can only travel about 50 mph with 4 wheel engaged but being that it does not have a transfer case does this make a difference? I just don't want to cause any damage. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
MSSLGECKO Posted December 11, 2006 Share Posted December 11, 2006 You can go as fast as you like! I've never had any ill effects, nor have I heard of any from others. Quote Link to comment Share on other sites More sharing options...
subeman90 Posted December 11, 2006 Share Posted December 11, 2006 take it to the end of the speedo if you can get there....its all good! Quote Link to comment Share on other sites More sharing options...
mikeshoup Posted December 11, 2006 Share Posted December 11, 2006 Just don't go super fast on dry pavement in 4WD. You run the risk of torque bind in a straight at higher speeds if there's any discrepancies in tire size difference. Quote Link to comment Share on other sites More sharing options...
Ross Posted December 11, 2006 Share Posted December 11, 2006 Try not to exceed mach 0.95, you might run into handling problems..... Quote Link to comment Share on other sites More sharing options...
jeffast Posted December 11, 2006 Share Posted December 11, 2006 for the sake of law enforcement and having experance's with police officers, i reccomend not exceeding the legal limit while in 4wd, but thats just me Quote Link to comment Share on other sites More sharing options...
nipper Posted December 11, 2006 Share Posted December 11, 2006 You do have a "transfer like case". It operates the same excpet of re routing power to the front wheels. Dont go more then 50 on dry pavement. You can get torque bind and it will make the car hard to steer. I have done 60 in 4wd high on 40 miles of snow covered (packed) /slushy highway with no problem (I was the only one on the road dumb enough to go to work). nipper Quote Link to comment Share on other sites More sharing options...

Nothing wrong with 4hi, but it tempts me to drive faster than I should on icy roads sometimes. Quote Link to comment Share on other sites More sharing options...

You run the risk of torque bind in a straight at higher speeds if there's any discrepancies in tire size difference. I've driven my brat for well over 1000km onroad in 4WD at speeds around 100km/h. No ill effects that I can see so far. But it does have the best 4sp trans I have seen. I would really like to see how long one of these boxes can last on pavement in 4WD. Just the other day I went for a drive and pulled into a car park forgetting I was in 4WD with a welded rear and axles in, and I was on 215 wide road tires. Was interesting I must say, but nothing broke. Quote Link to comment Share on other sites More sharing options...
4x4_Welder Posted December 12, 2006 Share Posted December 12, 2006 I've done about 3,000 miles at speeds up to 70, going back and forth between 4hi and 4low. Of course, that is with the front axles out- Quote Link to comment Share on other sites More sharing options...
Snowman Posted December 12, 2006 Share Posted December 12, 2006 I think I ran mine up to around 80 in 4wd once on an ice covered road. Run for hundreds of miles at a time at 60-70 mph, and the tranny was good as new when I parted the car out at around 190,000 miles. Quote Link to comment Share on other sites More sharing options...
subeman90 Posted December 12, 2006 Share Posted December 12, 2006 if you want to get technical...they tell you that if you have a brat and you are going to carry a very heavy load you should use 4wd. i believe I read this in an owners manual once.

Of course, that is with the front axles out- that just makes you 2wd, so you wouldnt have torque bind. nipper Quote Link to comment Share on other sites More sharing options...

Flowmastered87GL Posted December 12, 2006 Share Posted December 12, 2006 pretty much as fast as the car will go (reasonably and legally of course) I've gone 60 or so in 4WD hi and had the tach up pretty high in 4Lo 5th gear Of course this was on gravel... dont do it on pavement.

Virrdog Posted December 12, 2006 Share Posted December 12, 2006 I've done 80 on an unplowed highway in my old Brat. The engine note changes when you have it in 4wd and I didn't notice my speedo was nearly pegged. Quote Link to comment Share on other sites More sharing options...

Less stress on the axles if you use four of them instead of only two. The old landrovers from the 50's had the same issue, that they produced so much torque in low range they would break the rear axles, so you could only put it in low range if you also had it in 4wd.

jeffast Posted December 13, 2006 Share Posted December 13, 2006 nipper he has one stick for 4wd and anouther stick for hi and low, so he can use low 2wd for getting started on hills and such Quote Link to comment Share on other sites More sharing options...

Jack in Norfolk Posted December 13, 2006 Share Posted December 13, 2006 This thread brings up an interesting question that I have been meaning to ask. I listen to the radio program "Car Talk" on NPR. One morning a girl from Alaska called about her 86 4wd Subaru GL wagon. She said that her father and her brothers all put thier trucks in 4wd in October and left them that way until spring. She had been doing the same thing in the Sube. I guess she had heard not to do it and was calling to find out if it was bad for her car. They told her that if she operated the part time 4wd on dry pavement, it could cause the car to flip over. I have heard reasons why you aren't supposed to drive in "real" (not awd) 4wd on dry pavement, but never because you will flip. Have you guys ever heard this? Oh, and for the record, I used to drive 4 hours home from Harrisonburg in 4wd when it was snowing/sleeting/raining, usurally averaging around 70 mph.
